Identical Twins: Growing Up Apart

This clip shows two identical twins who were separated at birth, each unaware of the other’s existence until adulthood. The two exhibit very similar personalities, mannerisms, interests, hobbies, and physical appearances (even though one is heavier than the other). Each twin independently went into the same profession — firefighting. The clip surmises that genes play a significant role in people’s physical, emotional, social, and mental development.
