How close are we to this happening with the current crew force? (...i.e. not after the bid closes, but right now)

We must have a handful of Capt's who are over 60 already, but how old is our oldest FO?

I know one who's 58 1/2.

Have any FOs gone over 60 already?

Just wondering how much time the company/union has to respond to this issue?
