Yeah, take appropriate precautions with RoadID, maybe a satellite phone if you really want to be prepared, etc. But at some level, if this is what will really make you happy or be the focus of your life, then don't shy away from the risk.

I have a cousin who is a diver. Some years ago he had an event that almost killed him ("blebs"). He was advised that if he continued to dive, there was some risk of it returning, so for some years he didn't dive. But a couple of years ago, in his mid-60s, he returned to diving. When I asked the "what if" question, he said, basically, this is my bliss - my son is grown and independent, I have no career any longer, I don't want to rot in a rocking chair. He's been diving for a few years now without incident (well, except that a his chartered diving boat sunk off of Indonesia, but he was rescued), and he's got something to live for.

Why live forever if we don't do what we love?
