A fortnight ago, Veteran Diver Oyama met the bends...

A diver on a passing boat recommended taking Oyama ashore and stretching him out, head down, on a steep slope. This too was done. In the next 60 hours Oyama was alternately parboiled and marinated in the brine of Nagasaki...

When the diver comes to the surface, however, he must be decompressed slowly lest bubbles of helium give him painful, sometimes fatal "bends...

Collingwood once also gave his audience an authentic South American recipe, with step-by-step illustrations, on how to shrink a human head. An actual shrunken head was, of course, in camera range during the show...
