I used to barista 14 hours a day on my feet, and honestly it's less tiring than sitting in front of my computer writing code for less than 8 hours. I enjoy both, but there's something simply exhausting about the nature of code. Also did manager+QA work from morning to night at one point and it was far less tiring than both of the above. But I hear Sam Altman used to send 1200 emails a day (about 2-3 per minute at 8 hrs??) and I could never do that level of managerial work.
