If by "clicking your fingers," you mean "cracking your knuckles," then there is a large amount of evidence that says that this depletes the cartilage in your joints, thereby eventually causing arthritis. But this has not yet been proven. Although...err...it can't destroy brain cells...

Swish some vinegar around in your mouth. It won't hurt, but it will denature the viruses in the sore to make the sore stop hurting.

Hmm. What color was your father's hair before he went gray? And what color hair does your mother have?
