“Human sensitivity to wetness plays a role in many aspects of daily life. Whether feeling humidity, sweat or a damp towel, we often encounter stimuli that feel wet. Though it seems simple, feeling that something is wet is quite a feat because our skin does not have receptors that sense wetness. The concept of wetness, in fact, may be more of a "perceptual illusion" that our brain evokes based on our prior experiences with stimuli that we have learned are wet.”
You guys are idiots, if you blindfolded me I can easily detect wetness and the difference between cold and wet. I can feel viscosity and how lubricating it is. The internet will literally tell you anything to make it click on a link.
