Great health tip there Ted,
But due to the current climate I am on light refreshing beers (currently a bottle of Corona) and I think in terms of DVT resistance these are actually slightly more effective.
Actually one serious health tip.
I was suffering quite badly with tired eyes and headaches and I put this down to too many late nights working in a room with poor lighting and dark walls.
I think the brightness of the screen (which is set quite bright) with the darkness of the rest of the room was causing some form of eyestrain.
I took inspiration from the Philips Ambilight TV sets and fitted 4 high intensity white LED's to the back of my screen (pointing at the wall surface behind) these produce a light halo around the border of the screen which as well as looking quite natty seems to have reduced the effects of eyestrain I was getting.
