I'm 24.
Yeah, I'd say it's done growing
However, like your feet and your nose, it gets a little bigger over the whole course of your life - not bad, right?
If you have good circulation, and don't gain weight - your size hard will not decrease with age either. If currently, you improve your circulation, or you have weight to loose, it will get bigger.
I don't know about the genetic link, there are a lot of factors involved
My dad's is bigger than mine I know, he's also 3 or 4 inches taller than me. |
