I used to have a cartoon from an old Punch magazine framed on my office wall, (nicely in context, as I was chairing a PCT at the time, commissioning health and working with social care.)

It was two old blokes in high wing back chairs in a care home, looking out of the window at a solitary tree. One is saying to the other,"Just think. If we hadn't kicked the booze and fags, we would have missed all this."
