45. No kids. No wife. Just me and a cat. I choose whom I consider my family from among my friends. Beyond that, I doubt I'm in a stable enough situation to have more than that.
Nice thing when I hit the end of my 30s, people stopped asking me when I was going to get married and have kids. Just never had the urge for kids and figured if I didn't feel the desire it wouldn't be a good idea. Came close to marriage once or twice and I might again, but kids no.
I like kids. I like my brother's kids. I like my friends' kids. Just don't want my own.
