It's interesting in that as we're just hitting our 60's, we're thinking of now moving out further, to our property towards North Liberty, or, perhaps a lake house somewhere. My in-laws live west of town towards Crumstown. Always have had good emergency response over there. 3 miles past Mayflower.
We have a friend that's had two major heart attacks. The last one, (I may have told this story already) he was playing golf with a guy half his age. Last thing he remembers was walking up to the ball on one of the greens. Next thing, he wakes up in the hospital. Apparently, he had his 2nd major heart attack right on a green. Fortunately the guy half his age was a cardiologist and did CPR on him for about 15 minutes and saved his life. Very lucky.
Did you know an AED (Automated External Defibrillator ) costs less than $2K? Might be something to consider having around the homestead.
Don't know how much an internal one (ICD) costs. I do know our elderly neighbor had one implanted and it saved him half a dozen times. My young neighbor saw the old neighbor with his car stuck in the snow, shoveling away. So he stopped by and offered to shovel it out. Old guy said "Thanks, I think my defibrillator just went off." Young guy laughed. Old guy keeled over right in front of him.
Young guy calls 911. Before the fire department got there, the old guy was already talking to us. (I'd run out there when I saw them talking, looked away, and saw the old dude on the ground). We told him the ambulance was coming and he said "OK." When they got there, they were gonna put the old guy on a gurney, but he got up and started walking to his house.

They convinced him to turn around and walk to the ambulance and took him in for observation. Tough old dude.
Anyhow, always something to think about.
