I try not to get too rattled about things that aren't that important - there's a different outburst for when the kids are reaching for a knife in the kitchen versus the reaction I have when they just won't stop talking. And my wife and I have mellowed out as we've gone along.

I think it's easiest to teach by example. My dad didn't tell us to work hard; we just saw how hard he worked. I know I have shortcomings - like a short fuse - but I've learned you can't come home from a long day of work and snap at the kids.

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.
