For all the people who said they are scared… the only sure is to confront your fears… believe it or not, when i was young i was actually scared of heights (yes i do have a couple of flaws :snooty)… but to impress my brother i went on the pepsi max rollercoaster in Blackpool (which was the one of the scariest back in the day) and after that i became an adrenaline junkie… i’d go rock climbing regularly, would be the first to rush to any roller coaster, and did several bungee jumps…
A sky dive is not comparable to any of the above though… for those real adrenaline junkies out there, i say go for it… nothing is comparable to it… it is one of the best feelings ever, and becomes so addictive! 
there are many types such as freefall AFF, tandem and static line parachuting…And a word of warning… don’t tell your moms if you do it…
