I don't know all of what he's taking, but insulin for the diabetes for sure. He's had it for over 20 years I think, but he manages it well. I also think some if the anger is due to the fact he knows his body is wearing down. He was a big athlete in high school, and played every sport available at the time, and set school records in pretty much all of them. He also went into the army in the 50s and was stationed in Germany as an armored personnel carrier driver. In the past few years he's had to give up a lot of things, like driving, woodworking, and deer hunting. I think stopping hunting bothered him the most. The diabetes makes it difficult for him to pick his feet up, making it almost impossible to get to his blind on foot. Due to this, he bought a 4-wheeler and drove it sidesaddle so he could still hunt. Unfortunately he had to stop a few years ago. And yes, we know it's not really him, but some sort of illness that's doing all of this. We don't know how to get him to go to a doctor to get looked at, cuz even when he was all good, he was pretty stubborn. He would probably refuse to go due to thinking he's fine. I will say he still remembers to feed the birds every day. They live in the middle of nowhere in northern Michigan, so lots of songbirds are around, and every morning he spreads seeds all over the deck for them
