In matters of risk, no man is an island

He writes: “It is our business, not the state’s, to say what risks we take with our own health.”

That is mostly true, but not entirely.

It applies to the voluntary risks taken by a mountaineer, a skier or a rugby player. But not to those who deliberately drive down a country road at 100 mph.

Or to heavy smokers. I recall several non-smoking patients who died of lung cancer, probably acquired passively from their chain-smoking partners or colleagues. There are other examples.

The World War II dictum ‘coughs and sneezes spread diseases’ is still apt. As the Very Rev John Donne observed ‘No man is an island’.
