Why Do I Get Butterflies In My Stomach?

Why do we get goosebumps from music? Can you trust your gut instincts? What is love - and is it all in your head?In this eye-opening exploration of the body's hidden intelligence, scientist Ken Okona-Mensah reveals how your everyday choices, emotions, and behaviours are shaped - often without your awareness - by complex biological systems. From the microbes in your gut and chemicals in your sweat, to the rhythms of your heart and signals from your skin, Why Do I Get Butterflies In My Stomach? uncovers the unconscious biology driving everything from trust and attraction to disease, stress, and decision-making.Drawing on the latest research in neuroscience, genetics, and immunology, discover why the spleen resists cancer, how your heart's rhythms influence decision-making, how the microbes in your gut may be choosing your friends for you, a test to see how attractive you are, how to spot a liar, and much more.Packed with strange-but-true facts, evolutionary oddities, and plenty of 'ohhh, so that's why' moments, this book proves that biology isn't just something you learned in school - it's the reason you overthink texts, cry at commercials, and feel like a genius in the shower but can forget your own PIN.
