My childhood dream was to study mechanical engineering. After reading 'The Mysterious Island' - which I read 25 times as a boy - I thought that was the best thing a person could do. The engineer in the book knows mechanics and physics, and he creates a whole way of life on the island out of nothing. I wanted to be like that.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.

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.
