The Definition

Jumping is an ability
That most humans and many animals shares to some degree
It is the process putting once body off the ground for a short time
It is only ones own power
Usually by propelling oneself upward vial contraction
And then force for extention of the legs

In some cases the hight of the jump
May be increased by using a trampoline
Or by pushing down with the arms while playing frog
Some can jump up to reach something high
Jump over a fence or ditch or jump down
And one can jump while dancing ..
But jump also is the cinnamon for an acciting style of dancing
Just to freak out for some time
Now listen to the sounds of Rick' Michael and Lenix terminator
Please' Jump!
