Glad you love diving Magnus, but as someone with aquaphobia, it's not my cup of tea. :)

And it's not that I have a problem with any of those activities, or others doing it - especially if it's part of their job (i.e. military personnel). If you're getting paid to do that kind of stuff, then good on you. I just have trouble getting past the logic of it all. To wit:

Why jump out of a perfectly good airplane?
Why jump off a perfectly good bridge?
Why jump off a perfectly good boat?

If it's crashing, collapsing or sinking, then I get it.
