Abby: Every single second of every day, your body is very busy. You have several systems working in perfect harmony to make you healthy and strong.

Right now, your heart is beating. Your nerves are sensing. Your skin is protecting. Your stomach is digesting. Your lungs are breathing. Your muscles are flexing. And your bones are supporting.

Abby: Your body also has teachers giving the rest of your body directions about what to work on. The teachers are called glands, and the directions are called hormones. All of those systems are working all the time. Even when you're asleep, your body is busy, growing, fighting off germs, and making new energy. Taking care of all those systems in your body means making sure you get really good fuel including plenty of water and healthy foods like veggies, proteins, grains, fruit, and dairy. Sleep and nutritious foods definitely keep your body healthy and strong. But there's one more incredibly important way to feel awesome. You absolutely must have fun!

Abby: That's right. Running, jumping, dancing, climbing, moving, and even laughing, will keep you healthy, strong, and always ready for new and amazing adventures.
