Do you remember "Sitting is bad for you" post from Instructables blog?
That told us we shouldn't sit for a long time. We should have a break after a few sitting on a chair.
It's many hours I am sitting on a chair to work with PC, and I know it's not good.
But who can told me "Hey, It's time to break!" ?
Maybe "Health Reminder"!
Health reminder is a simple script that warn with a message box, when you should have a break.
That will help you to have a healthy body and intercept long sitting times!
