The Rio Olympics was inspiring – all that muscle, youth and striving stuff. So inspiring that I got back into swimming, which is no mean feat for an ample 40-something. Soon enough, of course, my shoulders began to crunch like a bag of gravel when I swung my arms over. I was always puffed. It was depressing. But I then started reading about ex-Olympians’ injuries and my spirits lifted. Things could be worse; a crunchy shoulder is nothing compared to an ex-Olympian’s career-ending foot injury. So I wondered: was it better to have had an Olympic career and fallen into disrepair, or to have never had an Olympic career at all?
