Q: How will you know when you are facing the computer too much?
A: When you start getting thick epidermis skin below your palm.

There's this like reddish patch just below of my palm. The skin texture is like harder compared to my palms. I got the feeling is because of the long hours on the mouse. At first got that reddish mark quite sometime ago. But i didn't bother. But now that reddish patch is starting to worry me ... i dont want some think yellow skin below my palm. ..Geek scar.
