Old Hippie did a similar thing right before disappearing. He said to me that he had signed up for the Army in 1979 because of the Iran Hostage Crisis. He deleted it a few minutes later before I could post my reply, and never redid it.
Perhaps because maybe he had recalled that he told me a couple years ago that he had signed up in 1983 when Reagan invaded Grenada. I scoffed at the time, as he was a bit (as in decades) past expiration date for a new recruit at the time, plus who even had time to join when that shindig was over in a couple of days. "Breaking news, guess who we had invaded yesterday"
