The office cubicle was invented by Robert Propst in 1968. His original design was called the Action Office System and provided “a social kind of privacy” for the worker.

The cheetah has “semi non-retractable” claws (almost like dog claws) that work like the cleats on a football shoe to give the cheetah a lot of traction when running. The pads of most cats’ paws are soft, but the cheetah’s pads are hard kind of like the rubber on a tire. This also helps them grip the ground when they are running so fast.
