The newest extreme sport- riding a chair on castors down the ramp.
This exercise is made especially exciting because one of the castors broke off, so the chair tips precariously.
Sometimes, one must direct the movement of the chair with their feet so they do not fall off the side of the ramp which
can cause various injuries.
As I'm sure you can imagine, this activity produces a thrill that cannot be found anywhere else and is comparable to
riding an enraged rhinoceros down a steep grassy hill while balancing your checkbook.
