Some of us stay a long time (6 or more hours) in front of the computer. We work all the day typing with the keyboard or moving the mouse. And we are humans (yes, it’s incredible, but it’s true), so we use to sweat.
This guy seems to have a mouse in his hand for long hours, so he has invented a way not to have sweaty hands. The page is in Finnish (and the Fish won’t help you), but photos speak by themselves.
