I am remembering that Buzz was an alcoholic for many years so he took more than his share of ‘the holy wine.’
The astronaut corps resembled the Wind Bunch. The movie “The Right Stuff” lightly touched on the military and test pilot culture but the book covered it in some good natured detail. Add in being tagged “the Second Man on the Moon” after Neil Armstrong, practically a choir boy (him and Glenn, something about those Ohio aviators), and it’s not at all surprising that Aldrin developed a drinking problem.
