the man she tells you to not worry about ! . #brain #human #edu

The man she tells you not to worry about has a biological advantage you cannot compete with. Her brain is not choosing him because of his looks or his money. It is choosing him because of something invisible that neither of them can control. Every person on Earth has a unique chemical scent created by their immune system genes called the MHC. And studies found that women are subconsciously attracted to men whose MHC is the most different from their own. In a famous experiment, scientists gave women t-shirts worn by different men and without knowing anything about them, the women consistently preferred the scent of men with the most genetically different immune systems. Her nose is literally "scaling" for the man who would give her the healthiest children and she has no idea it is happening. But it goes deeper than smell because women are also naturally drawn to deeper voices. And research confirmed that a lower voice pitch is directly linked to higher testosterone levels. That means the guy with the deep voice is not just sounding more attractive. His body is chemically signaling that he has more testosterone which her brain reads as stronger and more dominant without her ever making that decision consciously.
