All I'm saying is that if the right precautions aren't taken - such habbits might have a health effect. There is enough information available for one to be well informed on the subject before making their own decisions. And whatever that decision is is fine by me. I'd recommend that people visit the website for their government health departments and workers compensation board before saying just how minimal the risks are. Repetitive stress (in the form of carple tunnel) is also factor for those with improper workstations and poor typing habits.
Exactly! What may be ok for one person could be detremental to the health effects of someone else. In Health & Safety, most of it is guidelines, based on chance (Risk). Some people get affected, some dont, and to further add to what you're saying, if you're one of the unfortunate people who by no real medical explanation ends up getting Work Related Upper Limb Disorders or eye problems, you probably won't know it until 10 or 20 years down the line. One thing I have noticed is that I have to make a effort to maintain good posture, otherwise I find myself hunched over in the chair. That could cause back problems problems for me in the future if I don't keep an eye on it.
On the eye-strain bit, I found something that's helped me - I have my computer by the window, so I'm able to gaze out over the road every now and then, like when I'm pondering on a new idea, or sipping my coffee.
That's the whole basis for the Health & Safety Industry's take on things. I used to work as a H&S risk assessment consultant for a while, until I realised it wasn't what I wanted to do in life, and concentrated on my graphics design/computing background. The experience however was a real eye-opener, and I still get trade journals giving some stories about how health and safety disasters. I would say that any employer should make absolutely sure that they follow DSE guidelines, and have a health & safety policy to (at the very least) cover this. It could save compensation lawsuits in the future.
Back onto nostalga, I'm very nostalgic about my old Sam Coupe computer. It was a 256K (Became 512K as standard with the inclusion of an internal RAM plugin accessed by unscrewing a panel on the base of the computer), had 6 channel stereo sound, 256 colour graphics, and ran on a Zilog Z80-B processor. It was a great computer, you could plug in 1MB rampacks on the back. I still have 2 of them and haven't got the heart to throw them away, even though I never use them any more.
