You could if you tried, sure some people are blessed and it comes to them naturally but your laziness and lack of dedication is really whats stopping you. Do you think the chinese are just "smart"? The average one I meant wasn't anymore intelligent than the average american but they work their butts off.Lol so diet changes people's brains and make them smarter? You buggin'
How can I become an astrophysicist? By eating right? Lol. Intelligence is fixed just like your height.
And malnourishment has a huge impact on it
Also haven't you ever heard of the gut brain connection?
