Washington, July 04: Supermodel Heidi Klum refuses to go under the knife, insisting that growing older is a natural part of life.

The 35-year-old German beauty admits that she is proud of her developing aging lines, as they reflect life experiences.

The supermodel wants to tell age-obsessed women that growing older is natural.

"There`s something odd when you`re 35 or 40 and ironed to the max. You change with time, and it`s fine,” Contactmusic quoted her as saying.

“Everywhere there are these stand-up cards saying, `Have a little silicone while you get your roots done.` I want to be the opposite of that," she added.
