So you would think that Neil Armstrong, having been the FIRST guy on the moon, the one who got to say some of the most famous words in history, would have come home and spent most of his time naked on an island while nubile young women fed him chunks of that dehydrated ice cream. Instead, he basically treated his literally death-defying adventure as little more than a business trip. He was a pilot and an astronaut, so to him flying to the moon and back was just part of his job. Once he retired in 1971, he actively tried to become a normal person again, to the point that some people even considered him reclusive.
He went to some pretty extreme lengths not to be recognized.
