Let's dissect this. If someone doesn't like chicken salad sandwiches, they shouldn't eat them for lunch whether they are retired or working. If I want to complain about my gall bladder (which was removed 15 years ago), I would do so at work if I am at work.
That would reduce the argument to "working till you drop is a heck of a lot better than playing crappy golf at the country club".
I would suggest that we all should have the opportunity to pursue our dreams sometime before we die, and retirement is a good time to pursue them. Who is to say that golf is an unworthy dream?
Work involves doing what you must do to earn a living, whether you happen to feel like it or not. If someone prefers work to pursuing their dreams, then maybe they need to do some more introspection and self questioning about what their priorities really are.
If someone's work and their dreams coincide, more power to them. But I think that is not generally the case and when it isn't, retirement is not only justified - - it is something that we owe to ourselves.
