Do you think about how you take care of yourself as you work at your computer?

I guess you are talking about ergonomics while using the computer. If yes, here are important things to remember while in front of the computer: Your eyes should be in straight line with the top edge of your computer screen. Your elbow should not bend while typing on the keyboard and your chair height should be adjusted such that you don't have to bend your arms to type on the keyboard. Your chair's back should in straight line. Don't bend or stoop while using the computer. Your posture should be correct. Take a mini break every 10 minutes and take a macro break every 1 hour by having a walk, etc. Of late there has been a rise in computer-related diseases, we need to prevent it before it affects us.

yes. because body keeps giving signals.

Its easy to eat while on the front of PC. And computer won't leave on the desk so we are free to move. Its up to us if we will let this machine takeover on us...Which i dont think we will let happened.

your question and the type of reply that you want is unclear. is this pretaining to hygene?
