facebook is bad

Ok now I understand that most people my age use such things to keep in touch with people they went to high school with etc. I've recently tried this (by this I mean being friends with more than like the 12 actual people I normally talk to in my life). I promise this is not good. I mean its kind of good in that I feel like I look better than some at or around my age, but its is terrible in that I haven't seen some of these people in like ten+ years. What I learned is they are old. And clearly I've deduced from this that I in turn am old. Beside the fact that clearly my body is falling apart I don't feel old. I don't feel like I look old, but these people who are my age and younger look kind of old. Are they really old, do they just look old, or is it mearly that they were very young when last I saw or heard from them. Oh this is less fun then one would have thought. I guess this is what you get for wondering what happened to people.
