I enjoyed learning that when our skin temperature gets above 93 degrees, the heat sensors in out body trigger a cooling system; this cooling system can be the thing that keeps you alive in a dangerous situation. Sensors for heat are most prevalent in our fingertips, nose, and oddly our elbows.

It was interesting to learn that touch receptors are sensitive enough to feel a single beat of a fly's wing. I wonder if that is why we get random goosebumps when a slight cold draft comes by us.

I was surprised to learn that ordinarily our body produces 2 pints of sweat a day, but under extreme conditions, our body can produce up to 4 pints an hour of sweat, so long as it is replenished. I wonder if our body could produce more than that if we had more weight, or we were out of shape, or other factors.

I never knew that each square inch of your hand holds 600 touch sensors. Some touch sensors that are close to the surface record light touches, sorta like touching your phone screen; whereas the ones deeper measure harder touches, like pressing on a perfume nozzle. I wonder what would happen if something stimulated both the Surface and Deep touch sensors.
