A human body book with a twist—discover the science behind the weird and unusual stuff our bodies can do from Dr. Azmain Chowdhury, with illustrations from Daniel Nelson. You know your heart is always beating, your intestines digest your food, and even that your brain is still awake when you’re asleep—that’s no mystery. But why do we get "brain freeze" if we eat ice cream too quickly? And why on earth do we get butterflies in our stomach when we’re nervous? And is it true we can squirt milk from our eyes?! This book focuses on the bizarre things all of our bodies do—including things we don’t understand (looking at you, appendix). Dr. Azmain also asks the burning medical questions we’ve all been wondering about: Why does cilantro taste like soap to some people? How long can we stay awake for? Can our hearts actually break after a romantic break-up? (Asking for a friend). Filled with gross, surprising, and downright terrifying facts, it’s bloated with cool science to impress your friends.
