Biology or physiology? Because I believe they are different. I've actually passed all of them. I'm saying I've never seen an article citing significant psychological impacts on a person based on their physiology. Unless you're talking about extremes regarding a person's body that are outside of the vast majority of the population or something linked to one's health and well being, idk if I see it. Are you going to post anything to support your claim or just make personal jabs at me?
