Ever wonder why you yawn? Or why you feel the need to sneeze when you stare at the sun? These are the most random thoughts that run through our heads, but no one really knows the answers to.
1. Why do we yawn?

2. Why do we sneeze when we stare at the sun?
This is known as autosomal dominant compulsive helio-ophthalmic outbursts of sneezing syndrome; which is reflexive sneezing induced by light. Moving from a dim light to a well lit area or sunlight triggers this reflex.
3. What does the "K" stand for in K-Mart?

4. Why can't we tickle ourselves?
One of the reasons we can't tickle ourselves is because our brain is trained to respond by a person's movement. When we tickle ourselves, our brain anticipates the movement and prepares for the action by taking away the feeling of panic.

8. When you lose weight, where does it go?
