Of course, as you stated, we&#x27;d really need statistics for someone who was 30 years old in the 60s.<p>John Glenn, Neil Armstrong, Buzz Aldrin, Michael Collins and Edgar Mitchell are all at least several years beyond 78, with Glenn at an impressive 94.<p>By the way, the life expectancy at birth in that table is 76, so evidently reaching age 30 doesn&#x27;t actually count for as much as I thought it would.
