The wisdom of barbers
The trade of barbering is one of the world's oldest professions. The history of the trade varies depending on which culture is telling it, but barbers featured in ancient Greece and Rome, when their shops served as social centres and hubs for gossip.
In Europe, barbers for many centuries doubled as surgeons, blood-letting, abscess-lancing and wound-dressing as required. The trades eventually separated, but even today London's Worshipful Company of Barbers operates out of Barber-Surgeon Hall.
Barbers can range from the elite to the simple, and to their loyal customers they remain valued sources of gossip, information and even wisdom. Journalists love gossip too, so reporters from six of the BBC's language services went looking for ordinary barbers with exceptional stories.
