I recently had to see a very specialized surgeon for a medical condition that had to be monitored for several months. I didn't end up needing surgery but it was a possibility. The nearest hospital and specialist office are both 10 minutes from my house, with the surgeon in a group practice with someone on call 24 X 7. We think about moving from time to time but I realized some of the places we've thought about moving to might be an hour or two away from the specialized kind of medical care I recently needed. We didn't really buy our house with the thought of access to medical care, but now that we are older it is one of the reasons we've decided to stay put so far.
We have several senior clubs in the area, public transportation not too far away, one of the senior clubs has door to door bus mini-bus service, and one even has free Uber for seniors. With Instacart, the senior clubs for activities, senior bus and Uber, I think we could age in place here even if we couldn't drive any more. Plus we can walk to stores, our bank, restaurants, a post office and craft breweries. Most of that wasn't here when we moved to our neighborhood decades ago, but urban sprawl reached out and brought all these businesses with it.
