It's not that I particularly like sharks

I was reading a Fark thread (I know, stupid stupid stupid) and someone in it mentioned that sharks don't get cancer. Which sounded rather improbable, and indeed, sharks do get cancer. But anyway. Because people were, for so long, under the impression that sharks do not get cancer, shark cartilage became a fringe anti-cancer supplement. This seems a little silly to me--even accepting that sharks could not, in fact, get cancer, how exactly, I wonder, would eating their cartilage bestow that immunity upon a human? I don't see how a human could take advantage of a shark's supposed immunity to cancer except by, perhaps, turning into a shark. And eating shark cartilage does not, in fact, turn people into sharks. Unfortunately.

I just find it so revolting when people harm or kill animals for stupid reasons--eating them is one thing, but worthless "medical" treatments? (I'm looking at you, some parts of traditional Chinese medicine) Stupid. I mean, yeah, sometimes you harm or kill animals in the process of finding out that a treatment is worthless, and that's ok, so long as once you find out that it is worthless, you stop it.

Eh. This is what I do when no one calls the helpdesk. Stupid people not breaking anything today.
