Well, it might be useful because programmers are likely to spend even more time in front of a screen than the average person, and thus examples from other programmers might encourage them to exercise more. Other who sit for work find computers a necessary evil and prefer to do other things instead of working with them.
well we people just do all kind of stuff and that stuff never ends.. we feel like just few minutes but the reality is the time keep ticking and our eyes just stick to screens... and at that moment we dont even think about the health and body .
