Since people realized that you could jump out of airplanes for fun, skydiving has grown into a leisure activity, hobby and even a competitive sport. It's something that appears on many bucket lists, but you can turn a one-time experience into a professional career.
Skydiving is perhaps the original extreme sport, and it is entirely reasonable to wonder if it might be hard on your body. Without having ever jumped out of an airplane before, you could easily imagine that deploying a parachute at 120 miles per hour would put a lot of strain on your back - or any part of your body.
Lots of things we fear have very sensible roots, and being scared of heights is completely natural because falling off something is bad for you. But however sensible it feels to be anxious about skydiving, technology, technique, process and security should allow you to overcome that fear.
