So it's genetic. Do you believe that or are you just throwing that out there to answer my question? Saying it's genetic is a pretty extreme, hopeless position to take.
Why do you need to wait for people in the future to help you understand this? You have a whole group of people here to survey to gather information to deepen your understanding. If it's genetic then there are certain assumptions that we would all meet right? Do we all meet those assumptions? If you don't know, then why are you choosing to throw you hands up in the air and take a defeated position by telling yourself it's genetic?
