You are such a gem. This is an amazing essay. I bet your family is just as awesome. I'm sure you will live to 100! You are now in a place without much stress in addition to your healthy living. I had a friend who lived to 104 - one of the most amazing people I've ever met. He lead a healthy life mostly and exercised up until his 90s when he couldn't see great anymore. I bet that's whats in store for you. :)
