I think you're misinterpreting here. GP didn't make any generalizations about people in their 40's. They were providing additional context about a specific individual. Moreover, the context they were trying to convey was more about the delta in years of experience than a particular age bracket.
Also, thanks for the casual sarcasm, casual assumption of ill-will, casual tone policing of others according to your personal whims, casual accuse-first-rather-than-clarify and embarass-in-public-rather-than-confront-in-private approach. Really brightens the mood in here!
