Flexi Says: You have many reflexes. In fact, much of your behavior is made up of reflexes that protect you from danger in some way or the other. For example, gravity tries to make you fall over all the time every day. Without your having to think about it, your body constantly makes adjustments to keep you on your bicycle or even just in your chair. Simple reflexes make you blink when something gets too close to your eye and make you close your eye when dust gets into it. Vomiting is a more complex reflex that protects you from dangerous things in your stomach or throat.
