If you think of lawn bowls as a simple game where old people roll a ball slowly across the lawn, then you should meet Noorie Razack, the chief coach of Hong Kong Lawn Bowls Association.
Mr Razack - who has been coaching the game for 26 years - is the elder-statesman of Hong Kong lawn bowls. He is as energetic as a schoolboy and mentally as sharp as a straight-A student.
'You must use your brain to play this game,' said Mr Razack. This perhaps explains why lawn bowling is becoming an increasingly popular sport as more people, young and old, want to sharpen their body and mind rather than just spending hours in front of the computer or TV during their leisure time.
The origin of the game can be traced back several thousand years, to when the Egyptians played a game using rolling stones to knock over as many skittles as possible. The game then spread across the globe in various forms such as bocce in Italy or boules in France before being popularised in Britain.
While there are many rules in lawn bowls, the basic idea of the game is simple: throw a ball, or bowl, to a point that is the closest to the jack, which is a small white ball, to get points.
It may sound easy if you discard the fact that the bowl is lopsided and has an extra weight on one side. The bowls therefore require the lawn bowlers to deliver them in a precise manner so that they can curve along the way and stop at a certain point.
One of the most exciting aspects of lawn bowls is that it is also a mind game. For example, you can throw the bowls to certain positions to guard the jack or knock it away from your opponents' bowls. The skipper of each team draws up strategies for his players after analysing the positions of all the bowls in play.
