Well, when you're at terminal velocity... and you're smiling... your front teeth tend to get slightly cold and you get sensitive teeth. Well thats how I felt after I went skydiving for the first time.
Mike, Astrid and I did Tandem jumps at the JSC (about an hour out of JHB). We got it filmed and on DVD (although we still have to edit it and join the 3 videos together).
An amazing rush but once you're parachute opens everything's different. Beautifull would be one way to describe it.
Heard a funny story about tandem jumps the other day... Two people do a tandem jump and pull their chute immedately. They carry a six pack of beer with them and drink it on the way down.
