Loooking for oldest practicing Accountant on AW

I do not have any plans to retire, health permitting I intend to carryon for as long as I can.

I have a long way to go before getting to 60. I would be grateful to hear from 65+ years old practicing accountants. The older the better. It would be great to hear from 80 year old in practice. I intend to be one (I hope!).  I may even go to an accountancy franchior open day on my 80th birthday to talk about 10 year growth strategy! Constraining factor - my death!

Are clients okay with extra mature accountants? Don't they think passed it? Will he/she be able to do the work now?

I was surprised and pleased to see a question from a 50+ year old thinking of starting a practice - great!

I think accountancy is of one of those careers where we can carryon as long as health and brain function allows.
