Why do men turn mean when they hit middle age? An unfair assertion, or a question for the ages?

For Dr. Jed Diamond mid-life meanness in males is a fact of life. In fact, he's made it his life's work.

As a marraige and family counsellor, he's spent the last 45 years helping men with their relationships.

In doing so, he's seen the phenomenon of the male mid-life personality change so often, he's even come up with a name for it.

Irritable Man Syndrome (IMS) is the name Jed Diamond gives to the process that turns your darling Dr. Jeckyll into vile-tempered Doctor Hyde, and his new book is all about how to safeguard your relationship from such a monster.

Here's a sad thought to ponder over in this, the International Year of Biodiversity. One in 13 of New Zealand's native plants is now threatened with extinction.

Six plant species are already extinct, and even the popular garden plant the kakabeak is in serious trouble, with just one plant left in the wild.

Its authors are hoping a new book featuring 189 different New Zealand threatened plants will stir New Zealanders to action, and inspire them to not only save rare plants in the wild, but grow them in their gardens. Alison Ballance joins botanists Peter de Lange (pron LAING) and Jeremy Rolfe to hear more.
