I'm coming up on 64 and I've never heard this. Personally speaking, the older I get less emotions I have because I've seen and been through enough to keep them at bay and grow somewhat numb to it. It's not that I don't have empathy it's that I have less of it. I'm not sure where this "weepy old man syndrome" comes from. Now, when it comes to family that's another story. Right now both my father-in-law and my wife's aunt are just days away from dying and we're all very close. Watching my father-in-law is like reliving my own father's death with the exception my dad was in a coma and never had the chance to say goodby.
M wife has been in Kentucky for two weeks. I was there last week and going back in a few days then it's off to Guam
Not everyone gets this, far from it, but i do think it's a pretty significant percentage. It's usually most noticeable in those who were previously tough and went soft. Some have been weepy all along. Others just get harder and more crusty, a la Clint Eastwood.
Yes, also sorry to hear about your family. Caring about family isn't weepy, it's plain damn decent human.
