I speak without a mouth and hear without ears. I have no body, but I come alive with the wind. What am I?
Answer: Hiccups. A hiccup is an involuntary contraction of the diaphragm. They start spontaneously and stop equally unpredictably. No cure (holding breath, drinking water, being scared) has been scientifically proven. Hiccups appear to have no biological purpose.
