Thing is, anything and everything can be dangerous.
Swimming, boating and fishing, for example. While swimming you may drown, either by passing out (for whatever reason), hurting yourself (losing your ability to stay afloat) or getting dragged under (currents). Boating includes, apart from drowning which is the obvious one, things such as fire and gas from kitchen equipment. Fishing includes injuries (not deaths) from fishingequipment, drowning (mostly currents) and other types of accidents.
And yet, we do these things, especially during the summer, without worrying about dying. If we were to worry, we'd have no lives left to live.
Basically, at the end of the road, everyone dies. If you're lucky, you get to both live the life you want and not die before you feel you're done. If you're done at 40, and then die, then really there's no loss, but you're the only judge of that.
Wow, this was deep. Anyway, I'm not saying she was done with living in this specific case. I'd assume not, as most people would at least like to see 70, but I'm also going to guess she didn't have a lot of time to ponder these what-if questions. Going in a flash is, for me, a lot better than slowly dying during say, a dark night at sea.
