Catch anyone over 30 in a direct light, with an unflattering angle, and they're going to look rough.
Let's face it, as humans age - looks fade. Sometimes it's really bad, other times not so bad.
I'd say if No. 1 - don't smoke. No. 2 - don't substance abuse, No. 3 excercise, eat decent food and get a decent night's sleep. After that, it's heredity and heredity can be a bitch sometimes.
