60. The age doesn't bother me too much, but the lack of working knees does. How many shots do you take in a squatting or crouching position? Can't do it. I either stand or put one knee on the (wet/muddy/dirty/stony) ground. At the end of last year I migrated to a mirrorless camera with a flip-out screen which should give more options for viewpoint, but I'm so old-school I can never remember to use it. First camera was a Zenit B back in the mid-seventies. It was so manual you had to focus wide open then stop down to take the shot.
On the plus side, my sense of humour is still juvenile.
