Skydiving
According to the Oxford English Dictionary, skydiving is "the sport of jumping from an aircraft and performing acrobatic manoeuvres in the air under free fall before landing by parachute". Not everyone is able to sky dive due to the fact that some people are scared of heights and some have heart problems so they cannot therefore participate in dangerous activities which may cause their lives to be at risk.
Sky diving is therefore considered as a very fun activity and it is therefore also unique, experiencing it may actually make one discover things they have never discovered before. Skydiving can be done individually and with other people. Training is therefore required to go solo. "The jump can also be made from a helicopter or the bottom of a hot air balloon from 4000m or 13,000. Some thrill seekers attempt to skydive without a parachute whilst flying through the air, and instead rely on the small parachutes they have that professionals have put on them".
This may sound scary but at the end of the day it turns out very fun, I will be the greatest experience one could ever experience. "Most people are drawn to skydiving initially because of the 'adrenaline buzz' that is experienced when falling towards the ground. Freefalling is an out-of-this-world experience that feels more like floating than falling. This is because you are so high that you have no reference points to gauge your speed by. After the first few jumps the initial fear and adrenaline buzz will subside and you can start to enjoy the sport for more than just its excitement".(university of Portsmouth,2011)
