Edited to add: Except it really annoys me when people eat really loudly. It's not that it grosses me out, or anything like that, it is just really annoying. How hard is it to close your mouth and chew, rather than chomp and slurp all over the place?!?
I can study though ALMOST anything - but loud chewing is something that I just cannot work though.
