Everyone knows that electricity powers machines, but it is much less known that the same can be said about ourselves. The ability to read and understand written words, see and hear, think and speak, move arms and legs, and even be aware of one’s own “I” is due to the electrical activity of cells, which is initiated by ion channels. They regulate our life processes from the moment of conception to the last breath. This book is almost a detective story, dedicated to a special type of protein matter, the ion channel. She gives answers to many questions. What happens during a heart attack? Can you really die from fear? Why can an electric eel give an electric shock? How do poisons affect the body? What does Botox actually do? What saved James Bond when he was poisoned? Why do they eat fugu? Why are red and yellow tones predominant in Claude Monet's late paintings? Is love really a chemical phenomenon? The book is extremely educational for anyone interested in the nature of electricity and its role in our body.
