I ran my first marathon in Florida in 1985. I had never run more than nine miles.

I gave birth to my first son in April 1986. I thought it would be a good goal to get back in shape after having a baby if I ran the New York City Marathon. I ran in it November 1986. I had just shot the 'Sports Illustrated' swimsuit issue, so I was in great shape.

I never let myself get desperate.

I look at being older and gaining wisdom. I've learned to stay fit and healthy. I accept my body, my life, and my circumstances.

That is my most comfortable place: close-up beauty shots! I also love to stand and speak in front of people. I can get a bit nervous while I'm speaking, but I love to touch others with my message. TV hosting with a teleprompter is also a comfort zone. I love to nail the copy quickly with the right expression and facial expression. Delivery is key!

A supermodel needed to be able to be on 'Sports Illustrated,' to be able to walk runways, to be able to do beauty ads, to be on covers. And the girls now can no longer be on covers and be in the ads because your actresses have taken over all the jobs. I don't know what happened, but we want our jobs back.

The biggest change for me as a mom was realizing I needed to put someone else before me. Now the hardest part about the empty nest is learning to put myself first. I know that I have raised my sons to be big, strong, independent men who love God, themselves and care for others. I have to learn to let them have space and learn without me.
