It's definitely seems like a highly unusual thing to want to do, I wouldn't consider myself claustrophobic but that video made me sweat and kind of feel short of breathe.

Why people do that, I have no idea...on the other hand, I feel like maybe I'm judging people for doing something they feel compelled to do and that kind of makes my anxiety about it worse.

I mean, I don't understand it, but I guess that doesn't make it wrong.
