Models have a sell-by date. There are certain jobs I don't do anymore, like the young, sexy, cute things for teenagers, or even 25-year-old girls. I … - Heidi Klum

The ultimate beauty secret for a woman getting older is, Don't be too thin! When you are just muscle, you end up being gaunt in the face, and that makes you look older by 5 or 10 years. I don't think of getting older as looking better or worse; it's just different. You change, and that's OK. Life is about change. I don't have anxiety about it, so I'm not running to get Botox. Maybe that will change, but I don't think so. I feel comfortable in my skin and comfortable with aging, so I think it's OK that I get wrinkles.

In this job an illusion of beauty is sold which doesn’t really exist like that. It’s like a work of art, an act. I cry in front of the camera but am not really sad. I’ve just come from a job, am made-up and made to look beautiful with fantastic clothes and hair and nails all done.

I think my business is about people making you feel self-conscious. All eyeballs are on you when you're a model, when you're on the runway or in front of the camera, you're always looked up and down and back up, so that comes with the territory. But at the end of the day I feel like my parents gave me a good solid foundation. I know who I am and there are things I wouldn't do. I wouldn't starve myself, I also never wanted to chop my hair off when people said I should do this and I should do that. And I always knew who I was and said they're going to book me like this or not book me. I don't want to be a role model because I'm just a person too, so I can have mistakes and some people don't like what I do. People always push this role model thing on you. I just want to be a good role model for my children.
