My T is 59 and I have thought about that before. I just never brought it up. It kinda scared me to think about so I just stopped thinking about it. I figured it was none of my business in the first place. She is turning 60 this coming year..but now that I think about it more I don't really believe I have an issue of her retiring any time soon since she just opened her own practice about a year ago. She has been a T for a while, but she has been working in other practices. I also believe she is in good health. So even though it is a fear in a passing thought of mine I do not believe it is something I have to worry too much about. Just sucks to think about.
