I know. Was talking in terms of likelihood.
Either way, my hair is pretty much the same as Chicharito. I have a really good hairline but the crown has thinned a little for at least 2-3 years. My dad says that his also started at the crown. I'll be happy if my hairloss is the same as his. 20-30...
Yeah, I don't even know if he has had any hairloss. some people might just look like that in the back (mine is very similar). Both his dad and grandfather have good hair for their ages (at least from the front).
Does a mature crown (like mature hairline) exist?
Of course being in shape makes a huge difference. Look at the difference of the face of this guy (MMA fighter):
Good shape:
Awesome shape:
He doesn't even completely shave his head. Just shortens it down. When I started thinning myself I saw his horseshoe, I didn't even notice before...
