Annie Barnard, 17 Although I rarely play rugby, it's my favourite sport. I love watching it on TV or live [the Rugby Sevens]. I play tennis frequently, which is also a good game to watch. Becky Martyn, 14 I love rock climbing. During the few seconds when you're at the highest point, looking down at the people buzzing around below, it seems like all the chaos of life has nothing to do with you. Catalina Hwang, 14 Jumping on paved ground after heavy rain and watching water spurt out of the cracks while my pant cuffs get wet. Kim-ling Humphrey, 14 My two favourite sports are rugby and netball. Rugby because it's so much fun to watch and netball because it's the only sport I can play without making myself look like a complete idiot. I love watching Formula 1 as it's exciting and tense. My favourite sport to play is volleyball as it's a brilliant combination of fun, strategy and teamwork. Kate Hudson, 15 As much as I like netball, dance is my favourite sport (it is a sport!). It's great because you can do anything and everything - no matter how bizarre, it'll still be dancing. Tony Ng, 17 Playing badminton. I like its flexibility, and the movements are a kind of expression of physical beauty, I think. It's an absorbing, wonderful and somewhat unpredictable game. Adam Tam, 16 Rugby. The sense of adrenaline when you get the ball in your hands and make your first tackle - there's nothing like it. Paul Sargent, 16 Scuba diving. Diving allows me to enter a different world. It's a fantastic, surreal experience and an unusual feeling to breathe underwater.
