Mr. College Answer person knows well the attraction of the bright yellow flame on the tender college mind. Why, many were the days he used to play with a lighter and bits of paper in his dorm room, wiling away the hours until he could play mischievous and possibly illegal midnight pranks on the Chancellor. But many decades have passed since those glory days, and Mr. College Answer Person now realizes the awful, scarifying possibilities that arise when one plays with fire. Singed hands, for instance.

Most of my friends live in other states, and I only interact with them through online chats. Mr. College Answer Person has heard worse. As for working out, Mr. College Answer Person tried it once.
