Gut-wrenching

“How many cows will be killed to keep Roger Federer, the world’s best tennis player, in fresh racquets this year? Do the math: The Swiss master is said to go through an estimated 900 sets of strings a year. Since strings lose tension as they’re played — and since Federer is acutely attuned to his ever-changing equipment — he will use five to seven freshly strung Wilsons per match at this week’s Rogers Cup, which is fewer than the 10 to 12 he’ll use at a Grand Slam event… For the record, it takes three cows to make a full set of natural gut strings. That means Federer, who uses a half-set per racquet, is indebted to some 1,350 cattle per annum.” Dave Feschuk, Toronto Star
