I was thinking about that like two weeks ago... That's funny.
I recommend checking out the braverman test. This helps to map neurological balance to determine what your dominant and recessive tendencies are. I found out I had a GABA deficiency, Balanced it out, And now I am ambidextrous. Everyone has a dominant and recessive tendency, And depending on what that balance is, Leads to different substances that act on different receptors. You can take it online for free here. https://www.bravermantest.com/
