Some of you who left comments had great ideas for exercise on rainy days:

*Hannah goes to the YMCA with her mom

*Robbie plays basketball indoors

Here are some other ideas, some of which I've told you in PE class:

*Wii is fun and has lots of games

*Put on some music and do at least 5 minutes of aerobics

*If you have enough room, jump rope

*Practice curlups and pushups

*Walk up and down stairs for at least 2 minutes

*Do housework like laundry or sweeping (your parents will love you and its good exercise)

*Play Twister or charades with friends

Of course, you should ALWAYS ask your parents before trying any of these!

I read an article the other day that was very informative. Scientists studied people at an all-you-can-eat buffet and discovered that people's brains played a HUGE part in how much they ate. Most people think that your stomach controls how much you eat, but it's really your brain that is in control. Here's what they found:

1. People who use smaller plates eat less food. Why? Their brain THINKS they are eating more, so they feel fuller faster.

2. People who chew their food at least 20 times also eat less. Sounds crazy, right? But again, the more you chew, the more food your brain THINKS you are eating.

3. People who eat slowly eat less. Putting down your fork, having a conversation with your friend or family at the table and just going slow all help you feel fuller faster. And that means you eat less.

So try these the next time you eat. Use a smaller plate, chew at least 20 times before you swallow, and slow down. These 3 tricks can help you eat fewer calories, and maintain healthy body weight.

Someone asked me, "Is dark chocolate good for you?" The answer is, "Yes!" Scientists say dark chocolate is better for you than regular (milk) chocolate because it lowers blood pressure, and is high in antioxidants, which fight disease and remove toxins from your body. But be careful--dark chocolate does have calories, so eat it in moderation. Great question, Hannah!
