Having a hip replacement operation and open heart surgery to replace a damaged heart valve would put an end to playing competitive tennis for most older players.
But David Hawkes is not your average 68-year-old and continues to make his mark on the national seniors circuit.
The Tauranga Lawn player won his 36th national seniors title this summer in the over 65 years mixed doubles, with Tauranga's Sandy Tritt, and he was runner-up in the singles division.
Last week Hawkes was honoured with selection into a special club.
Tennis NZ Seniors commemorates its 40th anniversary this year and has created a special Over 35 Club to recognise players who have won 35 or more national titles. The age of eligibility for seniors is 35 today but it was 45 when Hawkes won his first seniors title in 1992.
