Hearing laughter primes your face to join in. Science says so.

Researchers have found that hearing someone laugh lights up the parts of your brain that prepare your facial muscles to laugh too. Your face starts getting ready before you have decided anything.

Who makes you laugh the hardest, no effort required?
