Skydivers have to be physically fit, attend classes and be certified before they can go on a jump. For people who just want to try it, they can enlist the services of a skydiving company who will assign someone to do it with them.
There are thousands of sky divers in the US and the number is still growing because there are over 400 skydiving centers scattered all across the country. Some are open all year round, seven days a week while there are some that are only open on weekends. This really depends on the weather conditions and the discretion of those who run it.
Although there is no minimum age for skydiving, most skydiving centers require the individual to be at least 18 years of age. You can still jump even if you are 60 years old as long as you are not epileptic, have heart ailments or obese.
Skydiving is a safe activity despite the fact that you travel at a high speed before finally landing on the ground. On average 35 out of two million people who jump are killed each year. The cause of death is carelessness while very rare is it caused by equipment failure.
This is why it is important for skydivers both amateur and professionals to be trained very well in the use of their equipment. After jumping a few times with someone and taking ground classes, you may soon want to try this on your own.
