It's not a course most might recommend for achieving sporting success, but Birkenhead bowler Peter Nathan reckons his triple bypass heart operation two months ago was a big factor in his winning his first North Harbour centre title last weekend.
Nathan, only a ninth year bowler, won the Harbour singles championship final, defying initial medical advice and some reservations from his Birkenhead club, which required him to get a medical clearance before allowing him to enter a competition.
That was given after he had assured his doctor and his surgeon that he had never felt healthier.
The only stipulation the surgeon made was that Nathan avoid lifting weights.
"Honestly, in the last few weeks I've never felt fitter," he says.
