Eighteen. I think I feel a lot older than I am since I am part of the older batch of children in my senior year. It's good to hear that TBT's community is generally my age.
I'm 28.. not sure if I posted this yet. It's pretty awesome getting older, because your mind evolves so much mentally that life becomes far more interesting and fun. Even though I'm not really that old, I feel like in the past 10 years my mind has evolved 20-30 years in a good way.
