The mail carrier someone mentioned sounds like a good idea. Of course he only comes once a day. 6 days a week (for now).
When I was about 62, I had an inguinal hernia which I did nothing about for over a year. I felt fine the whole time. It caused a strangulated bowel one night -- I felt fine that night too until the last moment.
I vomited about 9 times. throwing up so much liquid that I learned later I was seriously dehydrated. That had caused me to faint on the way to the toilet, twice each of the last 7 times. (Once half-way there, and once just as I got there.) I forget the details but I fainted 14 times, when I never had before. I would wake up immediately after fainting, even before I hit the floor iirc.
One of those times I landed on my back, between two pieces of furniture. I couldn't seem to roll over partly because of the furniture. and partly because i'm 50 pounds overweight, and lay there 10 or 15 minutes (I didn't actually vomit that time because there was nothing left inside me.) Finally I figured out how to twist around and get up. Instead of calling an ambulance, I went to bed, woke up in the morning and listened to the radio for a couple hours. . Then around noon I called a taxi and took it to the hospital emergency room. Proud of myself that I walked in, failed to notice how stupid I was. The doctor said I lost 7" of large intestine, that couldn't be used anymore, and it would have died at an increasing rate if I had gotten there any later. Which implies to me if I'd gotten there right away, I would have lost maybe nothing, or maybe 2 inches. Apparently we have enought extra bowel that 7" isn't much, and I can't tell that I'm missing any, but I'm still an idiot and I could have died.
I'm sure you're smart enough to get treated early on and this won't happen to you.
By coincidence, I also broke my arm at the wrist that last time I fainted. They fixed that too and my arm is perfect now, except my hand doesn't bend back quite as far as the other hand does, but I never do handstands anyhow.
