Question

why do people pee pants when scared.?​

Answer 1

Here’s your answer:
Some people urinate when they're frightened. Other people can't urinate when they're nervous. ... An area of the brainstem known as the pontine micturition center is in constant contact with the bladder. It knows when pressure is building, and makes the preliminary decision to void.
