Has moon walking got to do anything with a heart attack? Doesn’t make any link. But of the 77 NASA astronauts who have died, almost five times as many died in accidents as from problems with their heart or blood vessels.
According to a cardiovascular physiology expert at Florida State University the deaths of Irwin , Evans, and Armstrong at 61, 56 and 82 years respectively have at least one thing in common: all three flew to the moon. NASA reportedly is taking a close look at the cardiovascular issue for astronauts.
