That sounds so familiar - my grandpa repeated pretty much the exact same refrain starting in his late 70s! I do not think men handle old age well. He made it to 87 and was really annoyed at about it. A couple weeks before he died my mom and I went to visit him at his nursing home and his memory was going so he asked her why he was there and my mom said, "you have cancer." He goes, "really, is it going to kill me?" My mom tells him yes and he says, "excellent, finally!"
