Conditioning

Flea training, and how environment can condition us.

If you put a bunch of fleas in a jar and put a lid on it the fleas will jump and hit their head on the lid of the jar. They will continue to jump as fleas do and continue to hit their head until they get tired or get a real sore head and then they will stop hitting the lid. They will continue jumping though. After a while you can remove the lid and they won’t jump out because they have been conditioned to only jump so high.
