Need a lifestyle change - what is YOUR lifestyle and how can I change mine? HELP PLEASE> im 21?

well that was random lol. try going vegi thats wot I did. so much better for your health. there should be sports teams that are run at uni for the evenings, I don't know where u r but there's probably sailing clubs, foodball, rugby, maybe even a track team. see what you can find out in your students union.
