Dr. Donald Unger won the 2009 Ig Nobel for demonstrating (N=1) that knuckle-cracking doesn't lead to arthritis, by cracking the knuckles of one hand daily for 60 years, and never cracking those of the other.

- andegre 12y agoLike I said, for someone that does this NUMEROUS times a day, that is some EXTREME self-control to be able to only do it to one hand that long.
- Crito 12y agoWhen I don't crack my knuckles regularly, they start to feel extremely stiff and experience a dull pain. There is no way I'd be able to stop myself from cracking one of my hands for that long. That really is extraordinary self-control.
