You know what I just realized? I've been remembering bits of mental and physical health advice, like everyone else, and whether it's intentional or coincidence, they always seem to recommend stints in 20s. One piece of advice said that for every 20 minutes of studying you do, you take a short break, and that will help you learn faster without burning out too fast and boost your morale. An optometrist recommendation is that if you're spending a lot of time in front of a screen, looking up every 20 minutes and staring out at least 20 feet for 20 seconds will help prevent eye strain. Another recommendation says it's good for your digestive track if you chew your food for 20 seconds before swallowing, and it takes upwards of 15-20 minutes for your stomach to tell your brain it's full. There's even a rumored good exercise practice where, while walking, you occasionally run for about 20 minutes and then go back to walking; it's supposed to help keep your heart rate up without exhausting you.
I just thought that was interesting. Everything seems to be in parts of 20. I wonder if the sleep cycle has parts of 20 too...
