Numbers nationally: 3.4 million (85 per cent of them men).
Favourite locations: St Andrews and any club in the stockbroker belt, particularly the old course at Sunningdale and The Wisley (membership pounds 2,500 a year, plus an obligatory pounds 40,000 share in the golf course); the 19th hole (clubhouse bar).
Magazines: Golf World, Today's Golfer, Fore!, Golf Weekly, Golf Monthly, Golf Buyer.
Hazards: Bunkers; bushes; lakes; rain; lightning (on average, two of the five people killed every year by lightning in the UK are golfers); thieves (even second-hand clubs fetch a good price); being distracted by the adverts at the bottom of holes; being sued. A Scottish court recently awarded pounds 15,500 damages to a player injured by another's ball.
The kit: networking is as important as a good swing, so clothes must let you move freely and outbrand your rivals. Pringle or Ashworth jumpers and Callaway or Ping clubs are favourites. Each year British golfers spend pounds 155m on equipment, pounds 29m on footwear and pounds 64m on clothes. Callaway is now the sixth-fastest-growing company in the United States, and all because of Big Bertha - a metal driver Calllaway launched in 1991 and which every dedicated golfer must have (at pounds 230) each. The fact that neither a pounds 200 club nor dressing like an American tourist will improve your game is irrelevant. Golfers fall in love with their clubs. Those sleek, clean blades and slim graphite shafts do strange things to men. What other explanation can there be for those fluffy socks clubs are kept in?
