This is another article that I found today on livehacker (another website that I can recommend) where they write about a good method to avoid health problems if you are staring at your computer screen all day.
It's called the 20-20-20 rule and means that you should pause every 20 minutes, look at some object that is at least 20 feet away (I prefer a view out of the window) for 20 seconds.
Maybe it's not a high-tech news but I believe it's still important and I know I have to apply this rule to my working habits as well. The website also recommends software tools that can help you to find out when the next break is due (so you can even find some high-tech in this, can't you?)
