I will leave that to others, but one thing I will say is that having been around the business world since the early 80's I can typically date someone just by hearing what expressions and bullshit they use. Anything that we didn't use in the 80's appears strange to hear. For example back then we didn't use 'circle back' (and now I can't even remember what we used for that I think it was simply 'I wanted to get back in touch with you'..) And yes I know circle back has been around for a long time (could even have been late 80's or early 90's).
