Best wishes for the rest of your life.
Hi Jeff
Prior to my retirement former colleagues said 'you won't miss the job, but you will miss your workmates'. Within days after I retired I found that I didn't miss the job or the people I had worked with.
Enjoy your new life - there is a whole new world out there and for a young chap like you it's not too late to find something else interesting to fill in your time.
I enjoyed working with you over the years - even if you were a bit contrary at times, but I was always confident that your operational decisions were good ones.
I wish you all the very best in your 'retirement'.
