Fat ages you terribly. And even trying to lose the weight and become normal again often does not work. Your skin remains loose and your neck will sag when you lose the fat in it. This coupled with the fact that high amounts of sugar and alcohol also aging your skin(beer having large amounts of both), it's no surprise she looks 10 years older. A lot of women I went to college with kept their habits of getting drunk off of cheap beer every other night. Except now they are almost 30 and have just become the sad, delusional, aging party girl that's packed on 70lbs.
