That is why we and our future coming generations are very much more smarter than our ancestors. Our brain is so much bigger and can accommodate much more than those a few centuries ago.
There is an interesting fact referring to our usage of brain... Use it or lose it! Practice make perfect. The more we use, the better off our knowledge be. If we only keep installing and storing knowledge inside our brain by acquiring them, we might have missed out all those wisdom stored and inherited from our ancestors. Never underestimate what our mind can do when put into practice!
All of us have inborn genius that we inherit from our parents' ancestors and we have yet to really explore those depths inside our brain.
