I crack my knuckles quite often, mainly because they feel like they need to be cracked, I am sure you know the feeling. The way I normally crack my knuckles is just locking my fingers and stretching my arms, though I can often just move my fingers back without my other hand to crack them. Is this bad for me? I've looked at a couple pages (1) but I want you fellow smart people and knuckle crackers' opinions.
(I also roll my toes over and crack them, is this bad?)
