Jumping isn't my method but still an option.
What if you practice with Bungee Jumping to overcome survival instinct?
It's not the same feeling
I've been bungee jumping and it's utterly terrifying
You feel everything.
I've also been skydiving. Not scary besides the jumping part.
Also been cliff diving. I imagine this is the closest thing to the feeling of jumping. Not necessarily scary. There's no gut wrenching I'll murder you if you push me off AWWWWWW FUUUUCCKKKK there is with bungee jumping
