I'm going skydiving in a few days
Is this your first time?  I know that is something that I would even ever consider.  My fear of heights would render me completely lifeless.  So are you doing the real skydiving or in one of these indoor skydiving places?
It's the real deal! Tied to another person. It is my first time, and believe me I am scared out of my mind...but you only have one life to try new things assuming you don't go splat :D
Well, I am working my way up to taking a flight across the oceans perhaps one where I'm in a plane in the sky for over 8 hours.  Outside of that, I will give it to you that you are really brave.
