Common myth: skin wrinkles in water because of osmosis/swelling.

Reality: it is an active, involuntary vasomotor response. The nervous system constricts blood vessels under the skin to form ridges—acting like tire treads to channel away water and improve grip on wet objects. Patients with severed median nerves don't wrinkle at all.

This is also one of the things slop loves to add, spurious 'reasons' for things happening like my mother in law does.

Did she see the dog pee on some dead grass? That means if the dog pees literally anywhere it is going to kill the grass!
