One completely useless fact I love sharing comes from Bill Bryson’s book The Body: A Guide for Occupants.

Did you know that our skin doesn’t actually have dedicated receptors for wetness?

Think about it. We can feel hot, cold, pressure and touch, but our brain interprets whether something is wet using a combination of other sensory signals.

Isn’t it fascinating that something we experience every day is not quite what we think it is?

Perhaps that’s one of the reasons I enjoy reading books like this. They make ordinary things extraordinary.
