I'm So Glad To Learn This

A bit I crossed over today advises that:

The idea that knuckle cracking promotes arthritis was brought to you by the same old wives who warned that eyes can stay crossed and palms can grow hairy. No, there is no evidence that cracking your knuckles causes arthritis.

I hope this is true. I'm probably doomed to deal with arthritis anyway, but if arthritis were caused by knuckle-cracking then my doom becomes certain.
