I used to be grossed out at most smells and stuff and be a little maniac when it comes to hygiene. Now, unexplained, I smell my socks/underwear and other pieces of clothing in order to test whether they're dry or clean enough to use again. I just do it reflexively, without thinking it.
For some reason it feels perfectly normal, despite it being something I would never have done before. Now it feels more hygienic now that I have realized how much information can you gather from a piece of clothing just by smelling it.
