17. Comments Received from Respondents I'd just like to mention that my situation is a bit different than most. I'm on the swim team and if you had sent me this survey 2 months ago, i would have given completely different answers. I'm not in season right now so I'm not really exercising but when i am i work out like 8 times a week and eat a lot more food. i just wanted to make this clear.

If I happen to accidentally get the free exercise card, you should probably select someone else to receive it. While I appreciate the thought, I know I'd never use it.

18. Comments Received from Respondents (continued) This school sucks in everythingThis school sucks in everything Most people here are very unhealthy due to stress and the inability to deal with personal problems due to the heavy workload. Also this campus is extremely hostile and antisocial. People's personal lives and relationships are often suffering at the expense of school. The depression rate is very high and I have known people who have made attempts on their lives.Most people here are very unhealthy due to stress and the inability to deal with personal problems due to the heavy workload.

19. Comments Received From Respondents (continued) The Survey didn't really ask too many interesting or useful questions.Maybe you could try to correlate homework load with free time to do athletic stuff. Maybe you could try and investigate that people are eating sh**ty food on campus because that's all that's available around here. Oh, and CMU should relocate to California and get a Road Cycling Team ! Thanks. Hope you get an A :-)The Survey didn't really ask too many interesting or useful questions.Maybe you could try to correlate homework load with free time to do athletic stuff.
