No, I do not agree. We are not living in the stone age, we are living in the age of reason. We strive to overcome our primal instincts and live co-operative lives as social creatures living in harmony with one another. We restrain our natural self / instinct / id with higher thinking / rationale / logic / superego to not behave as the animals but rather as human beings. If the above is your approach to life, I wish you success and good luck, but for me it is the higher road of humanity and reason...Do you agree ? Nature want us to go Long way to happiness, because this mean you Will make sure that your body, mind,... Survive good. This is stage one, 2021 Stone age.
