First T was a lot older -- I was mid-20s and she was late 70s.

Random Ts I saw for a session or so were older by a few years to almost two decades or so.

Current T is just about 5-6 years older (she's early 40s and I'm late 30s).

I honestly had / have significant issues with all of them -- the only (almost invisible) silver lining has been that the issues were / are different.
