What have you done that is truly fearless?

I asked myself that today.
Sir Richard Branson has thrown down a challenge to find the most fearless Canadian as demonstrated in a YouTube video
The video must show someone doing something and being very brave. The clip must be made by a Canadian and will be used to kick off National Fearless Day in Canada

Virgin Mobile Canada has asked Sir Richard Branson to be the judge and he accepted. Its a great fit as Branson has accomplished so many truly fearless things - he sailed the Atlantic a few years back and went into space and has even circumnavigated the globe in a hot air balloon ... truly fearless stuff!Sir Richard surprised everyone when he announced that he would also be present to award the prize to the lucky winner. I can't wait until Nov 19 - what have I done that is truly fearless?
