ANSWERS

Stomach Growls?
Air in your stomach moves around and bumps against the contents of your stomach. The sound resonates through your tissues and comes out sounding like a growl. When you're hungry, the resulting muscle contractions in your stomach increase the growling. It's not like a dog's growl, but a hot dog or two would probably quiet it down.

Sleep?
Humans can go longer without food than without sleep. After several days without z's, insanity will set in. More than 10 days without sleep can be fatal. So get a good night's sleep!

Cooties?
Cooties are real organisms. They are a small, parasitic type of body louse similar to bird lice. They may even carry diseases like typhus. Thinking about cooties may give you the willies... but don't worry, willies aren't real.

Counting to a Billion?
If you could count at the rate of one number each second, without stopping to eat or sleep, it would take nearly 32 years (or 384 months) to count to a billion. So you'd better get started!

Sea Shell Sounds?
It is the sound of the seaÑyour own internal sea. It's actually the sound of your own blood coursing through your body that you hear.

Edible Clothing?
Your leather shoes. Shoe leather can actually provide enough nutrients to keep you alive for a short time. Talk about putting your foot in your mouth!
