When it comes to human body parts, some are more sensitive than others.

Lips and hands, for example, easily gather detailed information via sensory neurons. This is a vital survival function that enables us to safely navigate the world, from detecting a scalding cup of tea before taking a gulp, to noticing a bath is ice-cold before jumping in.

Thighs and forearms are at the other end of the spectrum of body parts, being much less sensitive.
