After the strain and struggle of being an astronaut in space, some don’t acclimate very well to regular life on Earth afterward. For instance, after leaving NASA, Buzz Aldrin had serious bouts with alcoholism and depression, got divorced twice, and became a Cadillac salesman. Lisa Nowak drove 900 miles no-stop from Houston to Orlando to attack Colleen Shipman, the new girlfriend of Nowak’s ex-boyfriend, astronaut Bill Oefelein.
