As a writer, it’s always important to pick up knowledge where you can find it.

I once had a roommate who had the worst case of dry skin ever (or so it seemed) and he was constantly in search of a better eczema treatment. At the time, it grossed me out; but now, I have enough knowledge that if I want to give a character a unique quirk, I know enough about this condition to write about it.

Strange how many things that you don’t consider important at the time come around to being useful later on. Especially true for writers.
