this will no doubt make things safer. Most all people on there computers can touch there screen from where they are sitting I bet thats you and you and you. This is not good especially in the long run. The radiation is bad. So this is what ive done . First chuck your optical mouse and stick with the one with the ball ( ball type ,they dont have radiation) -- next purchase 2 extentions , one for the key board and one for the mouse this means you can now sit up to 10 feet away from your computer ,, I sit about six feet away and only when its hard to read small print do i lean foward. Computers are here to stay ,,be wize. Oh yea try not to use any equipment that needs antenas exsample wireless routers. wireless key board ,,wireless mouses ,,they ALL put out radiation---you can also change your back ground color from WHITE (wich is the worst for you ) to a darker color like purple or green or blue its up to you --hope this helps--Kala
