Spent the back half of this day waiting on updates from 1200 miles away, as I couldn't get in touch with my father. It culminated with my aunt and several of my dad's neighbors prying open his back door to get to him, he was fully dressed and watching tv, but not breathing. Paramedics came and got him on oxygen, took him to the hospital. They ran a bunch of tests and apparently he has pneumonia due to aspirating, and though there doesn't appear to be any evidence of a heart attack and his old stents still look good and right, he went for an unknown amount of time without breathing. So we don't know if there's any associated damage there. Currently he's still there for monitoring and isn't really conscious, so... that's all I know for now. The guy retired about two weeks ago, I want him to be able to enjoy that, not have this happen. So just holding out for good news, and waiting for any news before I make plans to travel or not.
