Teaching kids about health and fitness is importan...

Age is no barrier. It's a limitation you put on your mind.

The London games mark the 24th anniversary of my winning two golds and setting the world record in the heptathlon. Someone is going to want it records are made to be broken - it's only a matter of time. I hope mine will outlive me.

My denial and irresponsible attitude about asthma put me at great risk and caused me so much needless suffering. My hope is that the kids I talk to learn to open up about their asthma, become educated about their condition, and seek help.

We talk a lot on 'Biggest Loser' about how fitness is a natural antidepressant, how it burns off stress. What I like about running is that it gives me time alone. I'm always busy, with people at work, with my kids. I love getting out for a run by myself and just listening to my music.

I personally love to run outdoor fitness trails. I love the meditative value I get when out alone, challenging myself to run faster and higher.

With fitness, I do Bikrams hot yoga. The gym that I have in my building is amazing. I love to do cardio and weights there.

I think exercise tests us in so many ways, our skills, our hearts, our ability to bounce back after setbacks. This is the inner beauty of sports and competition, and it can serve us all well as adult athletes.

After you're older, two things are possibly more important than any others: health and money.

You end up as you deserve. In old age you must put up with the face, the friends, the health, and the children you have earned.

Talk is by far the most accessible of pleasures. It costs nothing in money, it is all profit, it completes our education, founds and fosters our friendships, and can be enjoyed at any age and in almost any state of health.

My age and health will never allow me to realize the dream of art I've been pursuing all my life.
