Examples:
If I receive the results from a blood test and it shows my testosterone levels are well below average – not affected by any external factors. Why can’t my brain then send signals to create more testosterone?
If I’m feeling tired and can’t sleep, why can’t I sleep even though I need it?
Why is the brain just reactive and pro-active? Why are we not able to control things like the examples above? Is there a limit to how much our consciousness plays a part in our internal bodily functions? If so why? The part of the brain who handles consciousness is still part of the brain so why can’t it communicate these things?

> Why can’t my brain then send signals to create more testosterone?
Your brain is evolved through natural selection to work your body in a way in which it can survive. It has no innate understanding of the complex biochemistry that makes it function and there is no way being able to consciously control testosterone production would be beneficial to a simple animal. Once humans developed science to the point of discovering that testosterone exists the brain still lacked any conscious method of controlling it.
Think about the havoc something like a squirrel could cause in its own complex biochemistry if it could voluntarily control every aspect. How would a squirrel understand what cranking up serotonin would do? Is there a survival benefit for being able to stop its own heart at will? No! There is no reason for those abilities to naturally evolve so they didn’t.
