There have been a few deaths here & there - weather-related RTA's, falling trees, etc. - so not entirely a trivial matter. One guy in his 60's, who therefore should have known much better, died after falling thru ice on a boat lake in Danson Park, not 3 miles from where we live. We used to go there quite often when our kids were growing up.
Seems advancing years don't always equate with more wisdom or common sense. As someone famously once said, the trouble with common sense is that it's not very common.
