There are different qualities of boogers. Some are slimy due to colds, allergic reactions or exposure to harsh smells and chemicals. People who live in dry, dusty climates make drier boogers than those who in live in more humid places.
It takes a good bit of mucus to stay healthy. In fact, most swallow about a quart of mucus a day. To make sure the body has enough mucus to make boogers, it is important to stay hydrated.
