Problems related to health are evidently a very favourite topic on radio programmes.
Listening to one the other day, a lady presenter was expounding at length and with fervour the virtues of homeopathy.
I waited for the bald statement that homeopathic medicine had no scientific basis whatsoever but that never came.
Any beneficial effect of this kind of therapy can be safely attributed to a so-called placebo effect. Such is the power of auto-suggestion.
