I’m pretty athletic, and I like to play all kinds of sports. My parents ask me every morning to drink water at breakfast, and also during the day. I know it’s important, but for some reason I just can’t have water early in the day. As it gets hotter, any suggestions?—Jenna, 12, Upper West Side

I love soccer and I play it all the time, year round. But sometimes my ankle and knee hurts just a little bit, but I keep on playing and forget it since I don’t want to let my teammates down. Since I play a lot and it hurts only once in a while, I’m figuring that’s normal. Is it?—Justin, 13, Chelsea

I play on my school’s varsity basketball and baseball teams. Is playing two sports holding me back from becoming really great in just one of them? If I want to play in college, should I only focus on one?—Adam, 15, Sutton Place

“Kickboxers wear gloves but not shoes. Isn’t it easier to hurt your feat if they have nothing to protect them?” —Dax, 14 Greenwich Village

“There are all these articles and books coming out about soccer girls – just girls not boys – seriously hurting their knees. It’s hard to know what’s true and what’s not true. What should I believe?”
