Joan Vernikos was the former Director of NASA’s Life Sciences Division. Basically, she was responsible for understanding how to optimize the health and well-being of our astronauts. In this book, she walks us through how our sedentary lifestyles are surprisingly similar to the gravity-free lifestyles of astronauts in space. Just as an astronaut’s health rapidly deteriorates outside of gravity’s pull, OUR health erodes when we adopt a sedentary lifestyle. Big Ideas we cover include Gravity 101, why gravity is so N.E.A.T., how to build G-Habits and why your telomeres don’t like you sitting so much.
