When I first started to drive for Uber, and if I drove to the airport, I usually would call the day and turn off the new requests. After a while, I decided to leave the incoming request on (basically I didn’t do anything special), and twice I got a ride right away the the drop off location. Btw, in terminal one where most airlines fly, the ride share pickup location is near door 6 at the upper (departure) level.
This morning I was hoping for similar magic as I was driving my customers for flight. It didn’t happen right away. So I was pulling away before a request coming in – as I was driving I usually cannot see all details for the request. I accepted it. Turns out to be the beginning of a small disaster for me. The rider (customer) did a loop request for Uber (basically the pick up and drop off at the same location). And they didn’t speak English. They come to STL for an adventist world congress. After looping through airport a few times, and also attempt for them to call their son who speaks English, and also attempt to put in the new destination for the ride (was not successful), I finally gave up. I did what the ride request asked, dropped them off at the almost same spot. They did tip me one dollar.
This is one of the strangest Uber ride I did so far.
PS: early morning Uber driving
Since my most recent China trip, I resumed my Uber driving, and I drove almost entirely during early morning hours (after sunrise, in other words, I still don’t drive for Uber when it’s dark outside). I think early morning Uber-ing has a few benefits:
1) Airport rides. This is usually the most safe, and also sometimes people tip (because of luggages). And in rare cases, I got a new Uber ride at the airport (happened to me 3 times total, and with the last one I mentioned above).
2) People go to work or get off work. I have picked up people go to work (or get off work) at nursing home (this is probably the most common). But really I drove for people who works at Walgreens, Starbucks, Dierbergs, warehouse or assembly line, cannabis* store, hospitals, schools, office buildings and hotels. Basically pretty much anywhere you can think of. And this is as safe as airport ride.
*Cannabis: this is the smell I dislike when driving for Uber. I usually was not in a position or really like to tell people not to get on my car.
I have a Mac Mini, and I owned it for quite a few years now. I bought it at Costco St. Peters store, at around Christmas 2021. I used to use it to get to Citrix via Citrix Workspace, the remote desktop software that I used for work. The main reason I prefer this over the company provided IGEL product is I like the keyboard and touchPad for my Mac Mini better than the IGEL’s. I no longer uses Citrix as my employer switched to another software for remote work, also they provided a company laptop for work.
But I still have the Mac Mini, and sometimes I like to see my kids use the Mac Mini, instead of the laptop. Because the Mac Mini (the desktop) is in a public location, and I know what they are doing there. My older daughter (15) has the MacBook Air too: and not surprisingly she would goof around much more – aka doing TikTok etc. compared to do real things at the desktop.
Other benefits of a desktop computer is a larger display or screen, and family members can work on something together, if/when applicable. This is similar to the good old days, when we work in office, we have desktop or large screen, we can do pair programming or debugging together.
If you have limited budget, and don’t have extra money for Mac Mini or something similar, I fully understand. And if you have an extra display, you can still connect the laptop to the external display, to take advantage of the real estate. In fact, I think I have one or two extra external displays, if you are in STL area and are interested, shoot me an email at minjie dot xu at gmail dot com, and you can pick it up at my home at Olivette (aka 橄榄村)。
Separately, I just bought a new iPad for myself. I hope to use iPad more often (instead of iPhone). This has been my goal, but previous effort (a Samsung Android tablet) has been fallen short.
I started to learn Cantonese about 3 months ago, via Duolingo. I am still there (in terms of using Duolingo), but I think I should start to learn Cantonese beyond Duolingo.
I wrote about Cantonese songs as well (5 minutes read). People especially my friends could wonder: why learn Cantonese, especially now?
That’s a legit question.
For me, I think preserving the Chinese culture is a fun and rewarding endeavor. One fairly common consensus is Cantonese preserves the traditional Chinese the best: this is partially due to a decent size of Cantonese speaking people. Some stats on the English, Mandarin and Cantonese speaking population, from my blog post here. And I am pasting some stats below.
Google estimates there are 1.18 billion mandarin speakers in the world, vs 120 million cantonese speakers (refer to my blog post here 全球将近有1.2亿人口使用粤语 ). For comparison google search indicates there are 1.5 billion English speakers in the world.
My listand Playlist
Janice-卫兰: I started this list from Ayen何璟昕, who btw, is an excellent singer. Ayen何璟昕 was born in Guandong Province, and she sings in Cantonese, Mandarin and English. She is also a very good content creator, and last but not least, a pop music curator. This is something I realized as I saw she sung quite a few 副歌(英语:Refrain,惯称Chorus)and shared the short video on Douyin, WeChat and RedNote.
Last but not least, not 100% Cantonese (there are some Mandarin songs), nonetheless, I like to listen to them as background music at work (I work from home), or when I drive.
An old family picture (I published this photo earlier, actually, in this blog post). I talked a bit about my paternal grandma and my big uncle in that blog post.
Back: my grandma, my dad; Front (left to right), Minjie, and big bro, and my little big bro
Interestingly I saw that my grandma holds me, and my dad holds my little big bro. I think our mom was probably at work, and at the time she doesn’t have much freedom to walk off work. But in real world, my grandma likes me the most among 3 grand sons, my dad likes my little big bro the most, and my mom likes my big bro the most 🙂
I think this is probably taken in year 1974 or 1975. Let me will explain why. My big bro is wearing a red scarf 红领巾 which also means he already attends the primary school (or elementary school). You have to believe it’s red although it’s a black and white picture. Both my little big bro and I don’t have red scarf and we haven’t started attending primary school yet (we are all about 2 years apart), kids usually start attending elementary school at about age of 7 (in the case of our big bro, he was 6 and a half when he stared). My big bro started school on 09/01/1974, my little big bro on 09/01/1976 and I started school on 09/01/1978.
Back to my grandma
My grandma Zhang San’mei 张三妹 was born in year 1904. Her name 三妹 means she is the 3rd daughter of the family. She was born in 北仑霞浦. And she died in year 1988, in November 1988, when I was attending the Zhenhai Middle (High) School as a senior*.
Explanation about the High School in CHN: in China there are only 3 grades in school, and I was in the last year of high school. Note in China, the middle school includes both Junior Middle, which is equivalent to Junior High or Middle School in the USA. And Senior Middle, which is equivalent to Senior High in the USA.
My grandma gave birth to 7 kids: 6 girls and 1 boy (my dad, also he is also the youngest). Only 4 out 7 kids grew to their adulthood. My grandma sometimes would tell me the story of one daughter (she was probably between my two younger aunts 姑妈), and she was very beautiful. But she died before 14 or 16: I don’t know the exact age or circumstance under which she died. Keep in mind in those days girls were treated much worse than boys (I mean 1930s), and the fact they lived in rural areas does not help either.
My grandma is quite smart, as I talked about her smartness in my maternal grandma’s piece. Keep in mind 2 grandmas have different kinds of smarts: my paternal grandma can read a bit (she probably attended a few years of school when she was a little kid), my maternal grandma doesn’t read, but she has attention to details on household work and homemaking, cooking and sewing (mostly by hand). Also, I am both grandma’s favorite grandson, among my two older bro and me.
My primary caregiver
I have no memory of my grandpa because he died in December 1972, when I was only one year and 5 months old. My grandma helped my parents to raise us 3 boys – note this is very common arrangement in China, up until in recent decades. The social contract is we take care of our parents when they are aging, and the grandparents (our parents) usually help with babysitting when possible. This is pretty much true when my mom took care of my big brother’s daughter, and because they both live in Beilun, and also because both my mom and my dad were fairly young. They are each 53, and 52 years respectively, older than my niece – my big brother’s daughter. But I saw issues around those kinds of social contracts as increasingly one side doesn’t honor her/his side of the contract. Because it’s mainly just a custom, or moral responsibility, there are very little the justice system can do about it.
Back to caregiving part, as I think it’s more important. Keep in mind both my parents work full time even when we were babies (infants). Some of the job of taking care of babies fall to my grandmas (I think both my maternal and paternal grandma). Things such trivial as help baby fall into sleep or co-sleep. My understanding, in China co-sleeping with parents or grandparents when kids were little, is still quite common. I understand co-sleeping does cause other types of issues, which I am not getting into in this blog post.
She cooked and fed us
This is especially true in the summer breaks, when we spent about 2 months at our home in Xiao’men. I have said in other occasions, I did hide behind her back during vaccine drive, and especially when the Da Tou He Shang (大头和尚) showed up, during Chinese new year celebrations.
She has some money from my aunts – she would buy candies for us when she goes to the 小店; she saves moon cakes for us, they were sent by the aunts in Shanghai; she also buys fishes and cooks for us, sometimes.
Some fun episodes or stories
In most of her life, she doesn’t have a TV. Our family bought a TV in winter 1986 (note she passed away in fall 1988). She doesn’t understand or appreciate all the sports such as basketball, badminton, gymnastics or soccer. I recall we played badminton in the courtyard during very hot summer afternoon. We were kids then, and we were not that scared of the hot sun and so on. She just felt frustrated when we won’t listen to her and stop playing. She would say: boys, if you have that much of energy, why go to the fields or farm do some real farm work 🙂
Or Primary School if we use British English. But sometimes British English is cool, right? And btw, do you know that Indian English is more close to the British English?
Xiao‘men Elementary School 小门小学
Oh well, back to my topic. I started 1st grade at the age of 7 at Xiao‘men Elementary School 小门小学 (now 白峰宁国寺). Note: it used to be a temple before converting to the elementary school. My very rough guess was that the conversion happened in 1950s or 1960s.
My 1st teacher is Su Lao Shi 素老师,her real name is 胡素贞. I recall because there are other 胡老师,she took the 素老师 name. She is probably 5 to 10 years older than my mom (again very rough estimate). And my mom worked with her husband in the 小门大队。I vaguely recall 素老师 asked me the infamous “shooting at the birds on the tree” question (how many birds will be left on the branches if someone shot at the birds). 素老师 taught me both Chinese and Math from grade 1 to 3. I was a pretty serious learner then, as my teacher also told my mom “Minjie is sitting straight and his eyes are glued to the blackboard during our class”. In my recent China trip I learned from my dad that 素老师 passed way – she was probably in her late 80s 🙁
I did well in terms of academic performance at 小门小学. I recall we also participated some competitions at Bai’feng Elementary School 白峰中心小学 where all the kids from elementary schools in Bai’feng area compete. I recall once during the “listening words and write down words” competition, I did pretty well. Keep in mind many teachers in China at that time are very competitive, and 白峰中心小学 probably didn’t like the fact 小门小学 did better than them in some competitions. Because 白峰中心小学 is the organizer of all this, I think that’s probably one reason they didn’t run more competitions during my 3rd and 4thgrade. This is just my hunch though: I don’t have any evidence (too long time ago, and I was a little kid then).
As a side note: we as students actually sort of helped build the school at certain point. I recall we carrying bricks and this is probably unthinkable from western’s point of view (use kids or children as labor?).
My 2nd teacher is teacher Chen 陈老师。She teaches Chinese. And my 3rd teacher is teacher Xu 徐老师 who teaches math, and he is also my family friend. During the early days of my 5th grade, there was some change, that is my dad decided to move me from 小门小学 to 白峰中心小学.
Bai’feng Elementary School 白峰中心小学
Although I only studied there for less than one school year, I think I thrived quickly, especially on the Math. The math teacher there Mr. Zhang is quite creative, he used stars and quizzes etc. to encourage kids to study. And I did so well, and in the 2nd semester of my 5th grade, I was consistently ranked 1st on Math. My Chinese teacher and 班主任 teacher Hu was cool too. She was young and a bit strict. Once in her class she saw me spinning around with my pen that was gifted by my cousin in Shanghai. She took it and later returned it to me 🙂 She is a good teacher too.
And during the admission exam for middle school: I beat expectation again and I got into Zhen’hai Middle School. There is also an interesting math problem in the end during that exam. Here it goes, not exact words, the idea is the same.
======
Q: It takes 1 hour from Peter to walk from point A to point B; it takes Mike 2 hours to walk from point B to A. If they start at the same time, Peter from point A walking toward point B, Mike started at point B walking toward A. How long will it take before they meet (assume point A to B is a straight line). I will put the answer in the end. (I will put the anwser in the end. The word in town is only one out of thousands of kids in Zhenhai County was able to solve it.)
======
I also had quite a bit more fun interacting with friends in my grade. I recall we have at least two students whose dads worked close my dad (I mean the location, not the work area). There are also quite a few girls and they are very good academically too – in 小门小学 the class size is small, and I have fewer competitions. We do have one boy (whose father was the principal of Bai’feng Middle School for a long time), who is pretty good and went on to attend college (he and I are the only 2 kids in my 小门小学 class that graduated from college). Also another girl (whom I liked) went to become a nurse. At least in the beginning only 3 kids got out of the village after middle school.
Ayen何璟昕 He Jing’xin (earlier she used Ayen Ho for her English name) is very special and quite talented artist, musician and social media influencer (自媒体作者 zi mei ti zuo zhe). She was born in Guangdong Province and she lives in Beijing metro area now.
Sometimes people used the term “北漂(Baike, Wikipedia) bei’piao”。From what I observe, Bei’piao is quite common for musicians and some other artists, because Beijing is also China’s No. 1 culture center, in addition to be the capital of the country (the political center, and many good universities including the 2 leading ones). Here is an example of Shanghai singer who is also 北漂ing.
Live Performance
2025.10.18 CCTV 15 《15号音乐房子》 20251018 大概不到五分钟左右:漫步人生路;25分钟不到一点:祝福(粤语版);44分钟左右:人生何处不相逢(粤语),中间有一小段国语版 最真的梦。这里有粉丝团的剪辑版(微博)。Technically speaking, CCTV show is recorded not live. But I will categorize it as live as I think it still has a lot of pressure.
(Update 08-01-2025) I found an old video of Ayen何璟昕 on Bilibili – 56红人馆 第204期 南方姑娘何璟昕北上追音乐 小清新曲风书写心情. You may need a Bilibili account in order to watch. Personally, I have a Bilibili account which is tied to my WeChat account.
(Original June 2025) Here is my earlier post on her. The article was probably too long for a person who heard about Ayen何璟昕 the very first time. Below is an updated and a shorter version.
Also Bilibili: 南 屏 海 滩 it’s a combination of 南屏晚钟 (YT) and 上海滩。There are some similarities between those two song’s melodies.
Most of the video links go to Douyin 抖音. How to watch Douyin without an account? Basically, you need to complete the Chinese version of captcha (slide the shape/the object into its place). Also, you dismiss the phone number pop up after that. Btw, this is her Douyin live URL/address. Note I haven’t watched her live show yet, because before today 07-30-2025 I was under impression that we need a Douyin account in order to watch any live show. My assumption could be wrong.
Update 10-26-2025: also recently I happened to find another tip that get to DY on the mobile browser on the phone. That is the so.douyin.com DY’s own search engine. It only works on the phone though. It seems DY uses some “innovative” tricks on the front end.
(Original) I think this Douyin short video showed her skills very well. The song is 抖音《素顏》許嵩、何曼婷【動態歌詞Lyrics】Ayen was doing a cover, but it’s not a very straightforward cover. She puts efforts and creative thoughts into it. She has two versions of herself in the video.
And she did dance too. Ayen used to joke she didn’t know how to dance. I don’t know. But I know she learned dance in last few years. Personally I felt her dance move is good. Note dance is not her strong suite.
Top songs Ayen covered, many covered with acoustic guitar. This is a tough task, because I like many of her covered songs. I have created many playlists on YT or YT Music. Here is one example.
I noticed a QQ Music playlist created by a friend is also very popular – much more popular than my list – understandable from the point that in mainland China there are a lot more listeners for both Cantonese and mandarin songs, compared to the listeners outside CHN.
==================
Lullabies 催眠曲
Btw, for lullabies, my recommendation is to listen to them from a MP3 player, not from the phone. Because ideally, we don’t want to look at phone extensively before bed, and also, we want to keep the phone outside bedroom – for less distractions and better sleep. I learned this trick back in 2012, from the CEO of Arch Coal my employer at the time. But I had to admit I failed many times and recently I am more serious following this best practice. A related thing I started to do is to use Apple Watch to track my sleep.
That being said: here is my YT playlist for lullabies. I have a similar PL on my iPod Nano I use for sleep or before sleep (we are talking about lullabies or songs during sleep, right 🙂 I got the songs from Ayen’s Cover songs on the U drive.
This is my favorite lullaby right now 11-25-2025
A related thing I started to do recently is to use Apple Watch to track my sleep – after the suggestion of my 15-year-old. Previously I used Fitbit sleeping tracking for a while, but I haven’t used the Apple Watch sleep tracking since its debut in 2020 (I switched from Fitbit to Apple Watch a few years before that), mainly due to the fear to facing the reality of looking at my sleep data. Oh well, not a really good excuse and also let me back to the topic.
Similar singers
I saw some people commented on YT that that Hong Kong based 王菀之和陈洁丽的风格有点像Ayen何璟昕。我觉得读者可以自己去做判断。
PS:后记
How to show your support? Here is Ayen的店 at Taobao淘宝。She has her own branded guitar and other peripherals (附件,周边)in addition to her top selling Ayen翻唱經典歌曲集.
First impression: this is more like a feature phone instead of iPad Nano or smartphone. For $27 (before tax), this is expected though.
I already started to use the MP3 player and I tested out radio feature (it works). I haven’t tried the earphone comes with it. Right now I am using Apple EarPods. It meets my basic need.
Note another reason I need the MP3 player is it has better or more powerful battery than my current iPod Nano – it still works, but I don’t know how long it will last – I owned it for about 12 or 13 years.
PS:
I am thinking that I probably still will get the iPod Nano from eBay or somewhere. Ideally an iPod with good battery. Separately I bought the USB C EarPods from Amazon and really liked it too. I gave my old USB C EarPods to S6 for her school work (she has a school iPad with USB-C port, and she uses the EarPods for Map testing etc.)
Update (07-03-2015) It seems the player will drag the voice of a song, similar to how cassette player works when it runs out of battery or power. I need to verify it’s indeed the case. Once again more than 10 year old iPod Nano seems doing a much better job than this latest and greatest MP3 player 🙂
(Update 02-21-2026) I bought a refurb iPod nano from eBay over the holidays, and I sold the MP3 player I mentioned above.
The recommendation has increased the search for “iPods” on EBay more than 1,200 times an hour globally between January and October 2025, according to the company. The iPod third-generation models saw a 50% increase in average sales price from global EBay users in 2025 compared with 2023. The iPod Nano third generation saw a 60% increase, while the iPod Classic sixth generation had a 40% increase.
We cannot always be more talented than others – assume the nature born talent is “born”.
But we can always be more kind than others.
Example 1:
A rival tennis club owner trash talks about CCRC (Creve Coeur Racquet Club), ironically this owner is a fellow parent of kid in my younger daughter’s grade. Initially I thought about moving my daughter from CCRC (now Lifetime Fitness Creve Coeur) to that rival tennis club. Now I have some doubts whether I should move her. I do understand quite a few people moved before of the CCRC to Lifetime Fitness CC transition, including the coaches (the pros in the tennis world).
Example 2:
An internet singer I recently wrote, trash talks Coco Lee 李玟 ‘s perceived lack of mainland culture awareness in her mandarin education: 说她中文不正宗. This is totally unnecessary as Coco grew up mostly in the west. Quote a bit from her Wikipedia pagebelow:
Ferren Lee was born on 17 January 1975[19][20] in Hong Kong[6][16] or Wuhan.[21][22] She was a posthumous child, as her father had died earlier of an illness. She had physical defects in her left leg, which affected her throughout her life and contributed to her later challenges.[23] After her father’s death, Lee’s mother moved the family to Hong Kong to seek support from relatives. They faced difficult times there before emigrating to the US when Lee was nine years old.[24][25] She had two elder sisters, Carol and Nancy, the latter of whom would become Lee’s manager early in her career.[26] Growing up in San Francisco, Lee attended Redding Elementary School, Presidio Middle School, and Raoul Wallenberg Traditional High School.[27] She won the title of Miss Teen Chinatown San Francisco in 1991 at age 16.
Buffett and Munger
Now I recall Warren Buffett famously said “critique by category, not by name”. Charlie Munger may be a bit more critical on people in certain industry, e.g., cryptos.
In many ways we can out-work or work harder than others too. That’s topic for another day. But work smarter is equally important if not more.
(Update 06-30-2025) After a bit back and forth, the current status: the right AirPod has 18% battery, the left – zero. Will hang on for a bit (charing etc.) before finally ditching it to the local Apple Store 🙂
(Update 06-24-2025) It seems the battery didn’t last long. Out of battery after about 30 mins or so usage. I will continue monitoring.
(Orinigal 06-23-2025) 我用AirPods 和在eBay上卖一些小东西以来,可能最不可思议的一件事。Most incredible thing happened to my AirPods Pro 1st Gen, and in my 20 years eBay selling journey. Let me elaborate below.
Today I decided to try the “returned case” with the AirPods Pro 1st Gen that I left at home. First I charged the case and the AirPods. And then I used it with my iPhone 16, and it worked! My phone says “(my old daughter’s 1stst name)’s AirPods Pro”.
Are we talking about Headless chicken 🐓 or dead cat 🐈 bounce?
AirPods, top to bottom, Pro 1st gen, 3 and 4
Death Sentence
I sold the case via eBay in Apr 2025, as I cannot make the AirPods to work. So I thought the AirPods is already dead due to the age. I tried to charge the AirPods a few times, but it couldn’t connect to the phone after charing. Before all that we were visiting China (summer 2024), and I did recall sometimes my wife would take this away from her. And my wife may have left the AirPods Pro 1st Generation in her drawer for a long time. I am mildly annoyed by my wife policing our older daughter’s AirPods usage, if leaving it in her drawer accelerated the death, obviously I wasn’t happy, but probably at the same time I don’t want to fight my wife on this. There is this slogan: there are something in life money cannot buy; for everything else, there is MasterCard.
Now I think about it, perhaps leave it in the dust for a long time, may have helped the battery to come back to life? I know rechargeable batteries are not as predicable as the mechanical counterpart. Note I recycled my 1st AirPods at the Apple West County store. Since last year or 2, I am beefing up the eBay side business, and I was thinking maybe I can just sell the case because I assume the case is good.
I paid $159.87 for Apple AirPods Pro (series number: SH36DK17G0C6L) at Amazon on November 25, 2020, and I just saw it’s $219.99 on Amazon now.
I am not sad. The AirPods pro is about 2 years old. Typical life span for AirPods is about 2 to 3 years. The pro has two advantage that my AirPods 3 doesn’t have: 1) It can connect to my old MacBook Pro (late 2012 model); 2) It has noise cancellation. For the latter I have this Anker SoundCore headset.
Customer Return
But the customer complained it didn’t work, after he received the item. Note I could not verify it end to end before ship it. Fortunately I asked for the case back this time. Nowadays normally I let customers keep the merchandise and I would still issue the refund. This time I was a bit curious regarding why the case didn’t work for the customer. Now I think it’s likely due to the fact I didn’t remove the AirPods from my Apple account or resetting the device. Again I am not 100% sure. I did google search, and I recall I removed the AirPods Pro 1st Generation from all my iOS and Mac devices.
Earlier I talked about AirPods Pro 1st gen here as well. Let me copy some stuff over:
1st Generation AirPods Pro: purchased Nov 25, 2020, on Amazon. Died and trying to sell the case on eBay now). Update 04-13-2025: sold the case on eBay.
Now at least I can use this pair of AirPods as the spare AirPods in my car: just like we have spare tire in the car, now we have spare AirPods too 🙂
Lap pool (warm water, temperature is probably at 80F): 25 yards
Outdoor
They have two kinds of setups for the lap swimming
Shorter: about 25 yards
Longer: about 25 meters (about 27.43 yards)
Those numbers are a bit trickier because they are not standard. And I got it from my own try and error, via my Apple watch. I assume Apple watch is measuring the pool length correctly.
Need some confirmation as I haven’t been there for a long time.
(Update 06-24-2025)
Today (this evening) it was a bit usual because a boy approached me and asked whether I speak English. I said yes, and he asked if I could teach him to swim. It looks like he can swim to some extent. I showed him and his friend how to breeze via mouth above the water. Also, the very basics of breaststroke. The boy is 11, his friend is 9 and the boy’s big sister is 12. They all know some swimming or can swim some: but they seem have not taken formal swimming lessons at the J or somewhere equivalent.
I never in my life would think I would teach kids swimming. I never taught my own kids. I did teach my wife a bit re: breathing or blow the water (suck in air and leave the water out via mouth). I don’t mind teaching kids one a while, but if every time I go to lap swimming, and I could not find an empty or semi-empty lap, I may have 2nd thoughts on this.
(Update 06-25-2025)
I am continuing adjusting the length of the pool on my Apple Watch. Today I set it to 31 yards. This thing puzzles me a bit: if the Apple watch can measure my swimming distance, why it needs the pool length. It seems it’s using the pool length to do some kind of calibration, so that it could come up a nice round number for the total swimming distance.
