Working with a mix of boomers and millenials, I know I have to constantly remind my much younger employees what is not OK to discuss at work. Especially in the shop. Mostly because some things they'll discuss are inappropriate although none is particularly concerned about it.
It seems to me the data shows people become more concervative the older they are. It does not necessarily show an age-independent difference. How did baby boomers behave 40 years ago?
So no matter how old we are we will always love to Gossip and talk about Sex and Drugs. Just need Rock n' Roll and you could say we will forever exist in the 70's. :-)
