Britain's oldest judo master still teaching at 90

At 90 years of age, Bill Root is Britain's oldest judo master, still a fit fighter as he continues to teach the martial art after nearly three decades. The grandfather first took up judo at the age of 29 and has been an instructor for 59 years.

After having his own judo club for 30 years, Bill now focuses on training senior students aged 40 to 50 to be coaches. In each 90-minute session every Wednesday, he can be seen arm-locking and choking opponents, throwing them to the floor and holding them into submission.

Now a sixth Dan judoka – an instructor who is six degrees above a standard black belt – he wears a red-and-white belt which highlights his superiority in the sport.
