Since I started computer programming some years ago, I came to realize that a 24 hours day is very short. Sometimes I have to work for days with little or no sleep.

I always ask myself why a human body has (or needs) to rest (and most of all, sleep). Experts say that one needs at least 8 hours of sleep every day (of 24 hours).

So, is this an intended feature or it’s a design defect?
