It is hard, at times, to look at something or someone that you care about as the result of statistics. But it's true - we are all parts of various distributions, whether we know it or not. Some are happy (our long-tail-dwelling friend), and some are not (the poor souls whose cancers don't respond, or whose remissions are measured in days, not years).
I am simply happy that Leo's good health, and good luck, continue, and that he continues to be part of the Long Tail of outcomes. It's not only good for him - it's good for me, too!
