The world watched astonished as tennis veteran Andy Murray ground out a five hour and 45 minutes victory over Wimbledon finalist Thanasi Kokkinakis at the Australian Open earlier this month.

It would have been a magnificent performance for any athlete, but Murray was playing with a metal hip.

It is a feat Aquaculture Stewardship Council (ASC) CEO Chris Ninnes could empathize with all too easily.

Four months ago, Ninnes underwent hip replacement therapy, the side effect of more than 20 years of competitive rugby.
