Do you think most people in their 20's are addicted to alcohol or tv. Do you ever feel alienated?

I'm 26 and I don't drink and rarely watch television. Every time I meet new people in my age demographic it seems like everyone just hangs out and drinks talking about pop trivia or tv. I would rather mountain bike, workout, read about current scientific breakthrough, or educate myself. I'm in college working towards pre-pharm and/or gene therapy. I think maybe me being an older student has something to do with it, since most people my age have graduated/started a family/taken their first mortgage/etc. Sometimes I feel like something is wrong with me since I'd rather read up on stem cell research/technological advancements both medical and scientific/workout/bike or cook rather than drinking and talking about urkel. Am I weird?
