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. Thermoception The sense of heat (Or it's absence) on our skin.

2. Equilibrioception Our sense of balance - which is determined by the fluid containing cavities in the inner ear.

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

4. Proprioception Or `Body awareness`. This is the unconscious knowledge of where our body parts are without having to see or feel them, for example, close your eyes and waggle your foot in the air. You still know where it is in relation to the rest of you.
