I use high viscosity bean juice for protection
Along with a couple of friends I did a parachute jump many years ago.
When mentioning this to family and friends the question "who are you doing it for" seemed to be a involuntary reflex action*.
We were the only three on the course who weren't sponsored. We were doing because we wanted to. Any charity element would have been mere ego dressing.

*Mind you it wasn't as bad as the time cica 1990 when, upon us mentioning that we'd booked some flights, my sister-in-law, without a moments hesitation asked my (then) girlfriend if she would be buying a shell suit to travel in.
