I'd be happy just keeping the body i have now and growing a little more hair.
I have lost about 25% of my hair, but it's not THAT obvious yet.

Genetics can be a bitch. My brother was bald at 32, so i lucked out.
I have a weird shaped head, so shaving it would look funny.
I've had nice thick hair my entire life, it does suck to start and see it fall out.
