Why do we have a brain?

I found this, pretty interesting in regard to movement:

Wow! Now doesn't that just make you purr?

Beautiful.

Don't know how you found it but keep up the good work.

We have a brain to allow us to make adaptable and complex movements.

It seems that in the process the brain attempts to control the environment in which it allows us to make these adaptable and complex movements and that the 'desired' outcome of this environmental control is to reduce the need to make adaptable and complex movements or at least the big adaptable and complex movements? To put it another way the outcome is to reduce the number of survival situations (from jumping out of the path of a bus to starting a fire for heat) encountered over any period of time therby reducing the number of required movements and energy expenditure through muscle contraction.

In the short term the survival advantage of such a strategy is obvious but in the long term?

The brain is therefore responsible not only for creating the movement but for creating the desire to move. Now what are the implications of that?
