I'm 48 and about 40 I saw more weight gain and gray hairs. I'm not obsessed about looks though I do groom myself nicely daily so I really haven't fretted like I see many do. Oh well, life is short. Important thing is to be happy with yourself and what contribute. There's a woman at work that is grossly overweight. She also is unattractive. She has a better personality and is happier in life than many who look better than her are. She was recently diagnosed with multiple sclerosis. Still the same. Life is short so be happy and don't fret about what you can't change if you can't or if inside you really don't care and can change.
