I think the pastimes I’d want to try would likely kill me so Bones isn’t going to be able to fix me, e.g. freestyle mountain climbing, skydiving, bungee jumping.
I get the siren call of skydiving. Part of me is, “flying through the sky, wind blasting, amazing scenery.” Another part of me is, “Girl, you are talking about jumping out of a perfectly good plane.”
That’s my thought. There are a few things I can think of that come with a significantly higher risk of injury than death, though. I’d go hiking and camping more often (and in more places) if I didn’t have to worry about ticks and mosquitoes spreading disease. And if I could carry an effective antivenom, that would open up more of the world as well.
I’d try some harder mountain bike trails if broken bones were easy to fix. Of course you could still suffer a fatal head injury, but with a good helmet I’m more afraid of smaller (but still life-altering) injuries.
