Age has nothing to do with it, motivation does. I am amidst studying for a few exams right now and always know how to stir up some humor when I need it. I could care less about history of football, I hardly follow it other than both OU and OSU along with whatever NFL game may be on. Otherwise, med school has me flush to the grindstone. Bottom line, I am at college to get educated, not to debate sports (aka college politics) unless its for the greater good of humor.
I would definitely stick to medicine then. I hope u are a better Dr. than comedian...
