1989: What it's like to come down from the moon

In this 1989 interview, astronaut Buzz Aldrin frankly describes how his unstructured post-NASA life lead to mental health issues and alcoholism.

He also tells what it was like to walk in low gravity, how concerns about lunar germs that could cause a 'green cheese plague' kept the astronauts in isolation, and the round the world of trip the Apollo 11 astronauts took after their historic mission.

Aldrin was dogged by people who claimed the moon landing never happened.
