We had a discussion on the same subject with my mate Nick shortly before we left Cherbourg. He mentioned a remark made by a psychologist, who asked the question whether we are getting slower because we are getting older, or are we getting older because we are getting slower? In my case, the answer is clear. I refuse to be getting slower just because, at my age, that may be expected of me. But it’s a convenient excuse for all those coach potatoes.
