Heidi Klum

For me, my No. 1 priority in life was to always have a family. If I had not been able to work anymore, then that would have been it. I would definitely choose family over career. It's really great that my field has allowed me to work and let me do things that a woman does naturally.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.
