ok, lets see how clever you are

How come when you look in a mirror, left and right are reversed, but up and down are not?

Up and down and not reversed for the same reason that North, South, East and West are not reversed. They are absolute but left and right are relative to the viewer.

Edit: linguistic trivia

http://en.wikipedia.org/wiki/Guugu_Y...nguage#Grammar

The language is notable for its use of pure geographic directions (north, south, east, west) rather than egocentric directions (left, right, forward, backward).,[5] though such "purity" is disputed[6]

So presumably, you turn North, rather than left.

Up and down are also relative to the viewer you idjut.

Also we see the world upside down, the brain just compensates.

So if you stand on your head, does gravity work differently?

Because you've caught an unpleasant social disease from Mrs suity.

False argument. You are truly stupid. Up and down != gravity.

You have excrement for brains.

How come when you look in a mirror, left and right are reversed, but up and down are not?

Because the mirror reflects without reversing. Stuff at the bottom stays at the bottom, stuff at the left stays on the left etc.

When you look directly at something you are turned through half a circle and so left and right get swapped, but you don't have the same effect on up and down.

How come when you look in a mirror, left and right are reversed, but up and down are not?

Because your eyes are next to each other not one on top of the other.
