Which meant that some 70% of the time they did not scowl when angry. Instead, they did something else with their faces. People also scowled when they were not angry. "The scowl when they're concentrating, they scowl when someone tells them a bad joke, they scowl when they have gas, they scowl for lots of reasons,"says Dr Feldman Barrett.
