Such good advice! I am also 75. Although we'd long dreamed about moving to the wider open spaces beyond a metropolitan area, those are now fantasies. I've read of retirees moving to towns in Arizona or Colorado only to find doctors are reluctant to take on more Medicare patients in areas of high Medicare enrollees.

That is no surprise given the relatively low Medicare reimbursement rates to many doctors, especially those in primary care fields. We also have had to rely on the emergency room more than when we were younger, so now appreciate that we are close to good hospital emergency rooms.

There are many troubling issues with health care access bubbling up and already here. There is maldistribution by specialty and geography. There has been for decades but it seems worse today. There also seems to be a bottleneck in training programs, e.g., a lack of nursing programs.

In case this may be useful, here's a link to Triage Cancer. They provide all kinds of useful information and it is not just limited to cancer, though that has been a primary focus:
