Human biology doesn't change in 30-40 years.

90% of what doctors do is completely routine and they all know and keep up with what the "standard of care" is for common conditions and in many cases it's the same today as was the standard of care in 1984.

Sure, if you have something unusual you might want to go to a younger specialist or a specialty clinic where they focus on leading-edge care for that condition.

A 60-year old GP will do fine for your annual physical.

The biology doesn't change of course, but the procedures, drugs, medical devices, treatments and overall knowledge and best practices does.

An annual physical is such a small and simple subset of the total medical field so not sure why you bring it up.
