I've known a handful of people that I've essentially watched have a slow life meltdown because they started getting older and losing their looks. I really do believe great looks opens doors and sometimes keeps them open.
I know a guy who was soooo good looking when he was younger. His name was Duwee, believe it or not. Blond hair, blue eyes, great smile. Truly gorgeous when he was young. And boy did he know it. He ran with a fast gay crowd and was one of the pretty boys. And I think his looks likely got him jobs and generally made life easier for him. He didn't have to work as hard, could sort of phone it in at the office, and would get away with it because of his looks. Everyone wanted him around. But then when he started getting to middle age and things started softening, as it were, he found himself being held accountable at work more, and his relationships didn't go quite as well, and at some point lost his job, went into a downward spiral, started drinking heavily, and then lost his relationship and ended up essentially living with a friend until that friend kicked him out. Now he lives with his parents in a rural area and lets other people keep him housed and fed.
A good lesbian friend of mine, Jade, was truly stunning when she was younger. Definitely a lipstick lesbian with great clothes, gorgeous hair, etc. Really made an entrance and made a first impression. She was always invited to the best parties and everyone would always say "Oh Jade's here!" and be excited just because her pretty, stylish self simply walked in the door. Now, she's 55 and her cheeks are sagging, she has a superfine dusting of facial hair all over her face, and essentially spends her weekends in her bed, depressed most of the time, because her life isn't as fabulous as it once was.
Beauty won't stick around forever, people. You gotta have some brains and some game to back it up. Don't rely on it! It won't last!
