Where do you draw the line when it comes to plastic surgery?

I don't know what its called but I saw this woman on tv that was addicted to plastic surgery and she wanted to have her skin cut all the way around her stomach and stretch her skin to make it tighter. It was really sad, she thought she had to have all those surgeries. She was beautiful before she started but with all the procedures, she was looking a little nasty trying to make her self look good. It was really sad.. But, I don't want any surgery done ever again. I had augmentation and I don't regret it but Id never do anything else again
