I got codex to count my total heartbeats from my Garmin data. For four random days the counts were 72.252, 73.823, 68.922, 70.991.

According to google: "typical range for total heartbeats is 86,400 to 115,200 beats per day"

I run every day which would add a lot of beats, but my resting HR is 36 (pushed down by exercise i presume) with a daily average of 50 BPM. So in total a trained person may spend less of their heart beats.

Charlie Munger thought of exercise as adding mileage to the car.

I remember that a friend told that the Nintendo Wii Balance board gave her the weight on gram resolution. Which is 10-100x better than most commercial bathroom scales. But keep in mind that precision is not the same as accuracy.

A silly question (from a non-HW guy). Why are digital bathroom scales so coarse? Some have a weight resolution of +/- 500 grams. Would a better microcontroller make a weight faster or more presise? I guess this TI micro controller is overkill for a bathroom scale.

Hey. The "Prefer reduced motion" actually works. Neat.

However I am concerned that it may affect and mess up other things.

Good idea with the Zapper. It works for pages with an URL, but when opening a new tab there is no webpage to "zap", just the Google Doodle.

My solution now: Switch to other search engine (Brave/DuckDuckGo)

Thanks. Good idea. This is the easiest change to do while the World Cup lasts.

Thanks. I have uBlock. But it looks like with the latest Chrome it does not block

The animated Google doodles that appear when I open an new browser tab in Chrome is distracting. The Doodle is soccer/World cup animation. I want it to not animate.

I am not a coffee drinker, but I met with a friend at a cafe who said he was going to get a cup of insect poison, referring to coffee :)

This assumes that the article, the artifact, is most valuable. But often it is the process of writing the article that has the most value. Prism can be a nice tool for increasing output. But the second order consequence could be that the skill of deep thinking and writing will atrophy.

Some years ago I played a car game with Virtual Reality (VR). I noticed that it felt like the car was a part of me.

I wonder if the brain can experience if clothing, tools, bikes are part of the body?

Sure it would be cool, but I don't think not having 6k is my limiting factor (I have an ok 4k 42" monitor)
