Incredibly brave or foolish?

Foolish.

Its all good until you have a bad moment.....and we all do eventually.

Oh Man!  I stopped watching it during the first minute.  Scary.  Made me cringe and be glad that I was just sitting in my rollaway office chair watching a video instead of being in it.

Adrenaline a powerful aphrodisiac. You have to challenge yourself more and more to get the same rush. Few of these daredevils would qualify for life insurance.

Whew, it's scary even watching !

I can relate though, to be honest.  Sometimes when I go out on the porch in my jammies to get the morning newspaper I don't wear my slippers....what a rush!
