A lot of people don't want to know, but I'd like to know if I have a 10 percent or a 90 percent chance of developing Alzheimer's some day. If I know I'm likely to develop it, I'm certainly going to start looking around right now to find if there is something that I can do to offset it.

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.
