ALL/MOST of my friends click all of their fingers on every hand. They usually do it every period/lesson which is basically when each lesson starts (1 hour interval) I asked them "doesn't that cause arthritis" they said, no it's just bubbles. Is that true?

It's not arthritis, nor will it cause arthritis....it's simply relieving the pressure within the joint and in most cases, makes the joint feel better.
