So, like a lot of people focused on making lists, getting my inbox to zero, and all that good stuff, sometimes I'm not so good at the whole work life balance.  Even little stuff, like remembering to stand up and move around, before I realize I've been in front of a screen for eight hours and my legs are numb.

Which is where a little tool like Workrave comes in.  Every so often it will remind you to pause, stretch, focus further than 12 inches away.  There are options for different pause lengths, so they're not assuming that everyone needs to take a break at the same times.

 For Linux &  Windows, and the source code is available.
