A weird illusion is evoked once you stare at your reflection in a mirror. It’s a famous old Halloween trick that scientists are starting to explore. You can give it a try. Sit in a dark room, about a meter (3 ft) away from a mirror and stare at the reflection of your face for about ten minutes. Keep the room as dark as possible, while still being able to see your reflection.

Pessimists rejoice: happy-go-lucky, care-free peers of yours probably won’t live as long as you. New research suggests that the pessimists wind up outlasting the optimists.
