At work it's for focus and it really helps in that regards. The one in the car is to help me concentrate on my driving and fidget with when I'm not holding the wife's hand. And the one at home it's just something to fidget with. If I'm not fidgeting with it then I'm plucking out my eyelashes or ripping the skin around my nails. I'm a destructive person when I'm bored so it's something to occupy my hand with.
