I did consider going back in after 9/11. I actually emailed a Navy recruiter about joining as an officer, as by this time I had my college degree. I mentioned that I had been discharged medically after 5 years (though I think I may have cleared if tried again). I was discharged for what was then a chronic neck sprain after a car accident in Florida. Some dude was coked up and rammed into us at a very high rate of speed at a stoplight on the highway.
Anyway, I never heard back from the Naval recruiter and I said “fuck it, then.”
