Does this make sense to you?

This "vast ocean of knowledge" you're referring to is a cluster of autonomic functions not available to us consciously for very good reason. If you somehow gained access to any one of those then the system would be compromised and you would forever have to regulate that aspect on your own. Science knows everything about the human body with only one exception: the brain. Besides that, we know quite literally how everything works with very small gaps in knowledge that are being filled contemporarily.

Almost everyone in this thread is woefully under educated on even the most basic of scientific fact.

You seem to imply that science is the answer to everything and that what isnt proven by science doesnt exist. If science doesnt know everything about how a human brain works, how can you conclude that we are using 100% of our capacity? Has science tapped into those forbidden zones in our brain that would compromise (how did you know?) our body functionality?
