How old were you when you met your best friend ever? Are you still friends?

I was 35. Met her in HK. Still great friends now, although we don't meet so frequently. Friendships are strange. You can know someone for a long time since college and you think you were great friends but that friendship doesn't quite last when your paths diverge. But you can also have friends late in life but who really know you and do not judge you when things get rough and these friendships stay with us a long time.
