Why isn't there a separate fitness category?

Why isn't there a separate fitness category on Yahoo Answers that deals with resistance training and cardio? It's frustrating wading through the discussion about "fast" weight loss, green tea pills, the Atkins diet and dozen upon dozens of girls seeking positive reinforcement about their weight when they're likely suffering from eating disorders. It would be very nice to see a new category in the sports section for conditioning and make the Diet & Fitness section in the health category just for dieting.
