Office politics is one aspect. There are many news about the sudden death of programmers. Jia Jian has also studied this aspect. I heard from old employees that they overstretched their bodies when they were young, and often stayed up late to work overtime. When they got older, various diseases and problems would come. The programmer profession is particularly special, because this profession generally sits at the office and rarely walks around.
What health problems do programmers have:
1) Eye problems caused by staring at the computer screen
2) Back discomfort caused by improper sitting posture
3) Insufficient light causes vitamin D deficiency
4) General stiffness and pain from lack of stretching
Jia Jian basically has these problems. Except for some activities on the way to and from get off work, the rest of the time is basically sitting in an office chair.
