Book excerpt: It's pretty rare to come across a motor racing book that tempts you to read the thing in one sitting but "Prof" Watkins has produced a gem ... [he] is a superb raconteur, not afraid to speak him mind yet peppering the gravity with occasionally side-splitting humour. No true motorsport fan should be without this book.' Autosport Grand Prix racing has undergone sweeping changes in the last thirty years. Many of these involve safety and medical rescue. The man behind them - a champion in the racing world although he has never won a race - is the eminent neurosurgeon Sid Watkins. Life at the Limit is his remarkable story. It spans the most exciting years in Grand Prix racing and includes intimate portraits of motorsport's greatest names, from Jackie Stewart and Niki Lauda to Alain Prost and Damon Hill. Sid Watkins has also witnessed, at first hand, some of the most severe and spectacular racing accidents. His account of these is made all the more poignant by the fact that some of the men he has rescued, sometimes at the point of death, have been personal friends. From Monza, in 1978, where Ronnie Petersen suffered a fatal accident, to Imola in May 1994 where Ayrton Senna met his untimely death, the high, and low, points of Grand Prix racing are vividly described. For all fans of Formula One, this is the inside story of the world's most dangerous sport.
