People compulsively and dangerously obsess over many things, I think in our ancient history it was probably beneficial. I mean when you can catch polio from squatting in the woods, I think it probably kept many people alive by them obsessing over staying clean and doing routines and such.

Today, well I think it only hurts people. When no one really has to try to live past 30 obsession is very dangerous. I turned 21 yesterday, I've never had any form of disease or condition (besides psoriasis, which since I moved country the UV light of been more southern has completely removed it) and the only times I've ever been in hospital was once when I visited my dad because he had kidney stones and the other was visiting my mum at work.

My wife caught something, probably the influenza B outbreak that happened, and was sick for almost a week. Me? Not a thing, I've never had the flu I'm completely immune. My brother was bed ridden with the flu one time, my entire family had it except me... worst week ever! If I ever became a doctor I'd probably smother people.
