Why older men? All through my career, it was the younger folks who tended to treat the office as a social hub as well as the place they worked. As they got older, they'd develop more contacts in their communities through spouses, children, etc. and "fade" from the social swirl at work. At the very top of the age distribution you might find empty-nesters who have trouble connecting online, but those people were already leaving of the workforce (voluntarily plus ageism) so statistically I think they're outweighed by the youngsters who never knew any other way to meet people. What experience have you had that's different?
