Over time, football will make you dumber; all contact sports do this. I will do a bit of assuming here and guess you're going out with some chick who cakes on make-up and tries to make herself seem like the popular chick; if not, good for you, but there's tons of hot girls out there, so mentioning this affects no-one here. Also, if that's the words you use to describe your girlfriend, instead of touching on her personality, chances are, she's not that great(again, just assuming here).
As far as a 4.0 GPA, you realize it's easy to get a 4.0, right? As long as you do every single assignment and pay attention, there's very few people who couldn't get a 4.0 in this country. Besides, most of the most successful people in the world were college drop-outs; the creators of Facebook are a testament to this. And, being someone who is out of high school, and was bored at how easy assignments were in high school that I got a pretty low GPA, I'm doing WAY better than every single person that I knew from high school who had 4.0 GPA's. Also, I have done well enough in life that I, too, dropped out of college because I was successful enough that I didn't need to go.
So, OP, I'm sure you're just trolling, considering you're on a gaming website and claim to be such a jock, but, in case you're not, my words have been said.
