I've personally worked with doctors that had a lot more time because fewer patients see them in a day. They weren't older patients, necessarily, but this doctor (General Surgery department I think?) would only see around a dozen patients per day. Visits were scheduled for 15 mins, but could go longer if they needed it. This doctor had quite a lot of free time. It was a moderately-sized hospital in the Midwest.
