Ok this whole old age thing is killing me ( 25 ). Somone at work was talking about anti oxidants and if your an active person there are more free radicals (mumbo jumbo) floating around in you than a couch potato so you need to take supplements. Basically he was saying if you work out and don't take supplements you do more damage to your body than just sitting around the house. Whats the deal here? I need to get in shape and stop my knees and back from creaking.
