I have a habit cracking my knuckles. I have read many medical articles where many scientists and doctors agrees that that can annoy and gross people out it's not harmful and like when you are stretching then you will not get a cramp when you are running.

I can crack my knuckles I will not mention when someone does it although, that person starts doing a lot. I feel I need to say if they could not do it for a while.

How are you on this opinion?
