My idea is very simple. A mandatory 5 minute break every hour, at the top of the hour, for all computer work activity. Enforced electronically by disabling program operations on the computer for that time.

I have been a professional online poker player for years. Typically I would work with intense concentration for as long as possible, sometimes all day without a moment's break.

Eventually, online poker sites began the implementation of mandatory 5 minute breaks every hour, for all tournaments being played and at the same time.

It's easy for time to pass quickly during computer work. The mandatory breaks compelled me to do the little things that improve life, but are often postponed/ignored. Things like using the lavatory, standing up to stretch, getting a drink or bite eat, letting the dog in/out...etc

A five minute break/hr is almost 10% of time at work, but it has a dramatic effect on productivity and quality of life that more than compensates.
