I am going to rank this list from Impossible to Possible.
1. Wing suit from the top of Everest.
I want to do that once, just because it seems cool. But I know with my physique, I would not make it far. But still a thrill to think about.
2. Fuck while reentering and freefalling to earth.
Of all the places to fuck, the mile high club seems cool. But what if you can fuck during reentry from space? James Bond did in Moonraker. But I think its possible, given the escape pods from the space shuttle or ISS. Boy what a rush of a fuck.
3. Reenact the scene from Moby Dick.
Not that I believe in hunting anything for sport, but Melville wrote that scene to be thrilling. Standing in the cold, harpoon in hand, man versus nature, and man versus his own nature.
4. Dive the Bermuda Triangle.
I would have to go analog with my gear, as I use electronic gauges, but still I want to dive there.
5. Fuck on a Volcano.
Not erupting, unless me and wife are going to die anyways of terminal illness, but livestream to our friends us fucking on a volcano. I think you own the world if you do, might have to check the rules.
6. Go to space, just once with the wife, may include fucking.
Zero gravity sex.
I will add more as they pop in my head.
