You look like you're in your late twenties perhaps (?), but taking in consideration all the things you've done in your life, my guess is your maybe in your mid to late thirties ? (. Or more?...)... in any case, smoking and alcohol abuse are probably the worse culprits in the aging process,...followed by over eating and for sure stress..... but, as my hubby always tells me ( and has been doing so for years), it's more importent to take care of your inner self,...because when your looks fail ( as they most certainly will), the inner person is all that you will be left with...I think aging gracefully means becoming a better / nicer person...there's nothing worse than being around an irritated, nasty, self-centered, complaining old grouch....
