Thanks to both of you. All are good points.
No. Not contagioius - but - your peers can highly influence your thoughts/actions.
Close friends often where similar clothes, like similar music, etc., so, it is quite possible peers (at any age) can pick up not-so-good habits as well.

I would agree. Though I'm not sure contagious is the right word. My best friend in highschool was anorexic and I've struggled with it for the last 4-5 years. I think the reason it's "contagious" is because I saw how my friend lost alot of weight so in my mind not eating works. So I started doing the same thing.
