Tidbits - Learning Hat with a Little Humor
Why do we get Goose Bumps?
Gooseflesh, chicken skin, or cutis anserina, the technical name for goose bumps, starts with a stimulus like cold, fright, or excitement that triggers an involuntary nervous system reaction.
In humans, goose bumps are nothing more than physical proof that the nervous system is responding to the world around it, as it should.
Animals experience a similar phenomenon when they bristle, but they make good use of the big-hair effect.
If a cat's really chilly, its fur will stand on end, causing the elevated hairs to trap a greater amount of air close to its warm body. Or, if it's confronted by a foe, it will look bigger and more intimidating.
We humans just look, well, like plucked chickens.;-)
