When people talking about 'finding a new high' they hardly mean literally jumping 20 feet up in the air. I know I'm a special person for loving to run, jump and play since I was a kid. Dancing for about ten years after doing basic gymnastics (including a round off, back handspring --with a spotter, thanks, Janice!) until I was 14 was also after doing sports such as soccer, basketball, softball and track in my early teens.
So Maybe I jump a little farther or higher than the average 54 year old..but how I did the 20 foot jump with ease and repetition was with the help of a bungee jumping
