I crack my knuckles, and i don't want to stop unless it will hurt me later in life (which i am not sure of)

It will....If you crack your knuckles you are reliving pressare that doesn't need to be. It can swell up your fingers and really mess up your joints. They will crack on their own.

Knuckle cracking doesn't cause arthritis or anything. It's just air. -_-
