12 years after graduation: only 2 of my (former) highschool friends are bald

However that is not the same as male pattern baldness, that's a different beast. Male pattern baldness is NOT common, and a majority of guys even in their 30s are not balding.

Idk, (in my country at least) seeing a guy in his 30's without a level of male pattern baldness is rare.
