I'll let you know.
Last I heard, you're supposed to take after your mother's father...but in my case, so far, so good.
I do have some widow's peak (since my teens), and I think I notice just a little bit of thinning at the front maybe lately? But maybe it's just in my head. I don't notice anything half as drastic as others in my family.
