I'd like to think that, if I'm lucky enough to exceed the age of 80, with all my marbles and my more important faculties all present and correct, I'll be cut some slack in the matter of my more treasured bad habits. I'll feel that, having survived so long indulging my relatively few vices, I might as well head for the exit in a like manner.
I started thinking - how often do people put themselves at risk in the pursuit of good health? How often do people end up injured, in hospital or left needing long-term treatment because of skiing or other leisure activities? What's the cost of sporting injuries, both to our health and financially, in comparison to being inactive?
