G_STRING,
I was older than you before I ever considered setting foot inside a helicopter...don't ask by how much; haven't you noticed that this lady NEVER gives away her age.
But those who've met me know that I'm not the sweet young thing I sometimes pretend to be.
This isn't a second career for me; it's about the sixth! There are no age limits for instructing, so long as you can pass medicals...and Class 1 if you want to be paid. And in practice it doesn't seem to be an issue in the instructing world. I'm planning on carry on till I'm 90...so long as I can still climb into a helicopter. You, my friend, are just a kid...so stop worrying. And I agree with pa42; who cares what anyone else thinks; if you want to instruct, go for it!
