My T is probably in her mid 30s. I say that because she has like 2 different bachelor degrees, 2 different master's degrees, and 1 PhD. That's a lot of years of education which makes part of me think she's older than that but then she just had a kid 3 years ago and she wasn't considered high risk (which starts at 35 now). Regardless, it's a good working relationship for me. She can play lots of roles with me, from being a hard ***** to being very kind and mentor-ish. It works well. I agree with the statements that older Ts can be very good because they have lots of experience and I also agree that they do need to stay up to date with current directions in the field. Using techniques from 40 years ago probably wouldn't be as applicable or helpful today. I would probably consider seeing an older T if I needed a new one.
