Can we talk about how Henry’s medical leave was depicted in contrast to how such things were in the other novels?

Paul got holed up in that church hospital, where orderlies had to be flagged down and there were rumors of a room they brought men to die in. Henry got a total of four doctors to look at his knee, massages, baths, and chances to visit the town’s restaurants and horse races. It was as though he were on vacation instead of recuperating from injured legs.

What do you think Hemingway is trying to say by presenting Henry’s recovery to us this way?
