By rights, Ozzy Osbourne should not be alive. He spent forty years on a hell-raising, bat-biting, ant-snorting*, drink and drug-fuelled bender.
He broke his neck going two miles an hour on a quad bike and died twice in a chemically induced coma. And yet - at 62 years old - he is healthier and happier than ever.
He is a walking medical miracle. So who better to offer the public medical advice and support? In May 2010 the Sunday Times invited 'Dr' Ozzy to be their new Agony Uncle.
Since then he has answered questions ranging from dog depression to snoring to third nipples...and has also tackled more serious questions with his trademark humour and hard-won wisdom. The column has become such a phenomenon that Dr Ozzy has now decided to gather together all his advice into one handy guide.
Ozzy's motto is that if he can survive and enjoy a happy and healthy life - then anyone can.
And enjoy a very good laugh along the way.

* Yes. You read that right. Ant-snorting.
