im speculating on these two, but people who do a lot of blow and drink to excess frequently age themselves really fast, especially around the eyes. it's more acute than just frequent, heavy drinking.

the late 20-early 30s is when that divergence becomes noticeable, imo.

there are other environmental/lifestyle reasons for it, but that's my analysis of these two fuckups. if they keep it up, they're gonna look 50 by 35. and not in a sagacious way.
