Is it any wonder Martha Stewartmade historyas the oldestSports IllustratedSwimsuit Issue cover star at 81 years old?

Not that she wants it to look that way.

Thats why I really work hard at it.

I dont do fad diets and I dont do any pills or anything like that.

But I just eat really well and I watch what I eat.

Thats really the secret.

That, and a killer swimsuit collection.
