General Ignorance: How many senses does a human being have?

At least nine! The five senses we all know about- sight, hearing, taste, smell and touch- were first listed by Aristotle, who, while brilliant, often got things wrong.

There are four more commonly agreed senses:

1. the sense of heat (or its absence) on our skin

2. our sense of balance

3. the perception of pain from the skin, joints and body organs

4. body awareness, the unconscious knowledge of where our body parts are without being able to see or feel them
