@Kat919 - I like the story about your friend. I think the worst reason to have a cosmetic surgery procedure is to try to keep looking young - because it doesn't really work for that! Not for very long, at least.
But for people with a real problem, it can be life-changing. I had a cousin who had truly huge thighs. She almost couldn't wear pants at all because she couldn't get them over the lumps of fat. So she decided to have liposuction to remove those fat cells. Because she wasn't really doing it for weight loss, just to redistribute, it's been successful for her.
On the other hand, she did have some complications. Her incisions didn't heal as well as they should have and she had to go back in the hospital for a few days and get IV antibiotics. Wound up missing a fair bit of school (she was in college) and I think even had to withdraw from a class. But she says she would still choose to do it over again.
