We are ancient genomes in a modern world, and it's not going well. Modern humans are the most overweight, depressed, medicated and addicted cohort of adults that has ever lived, yet life has never been so good! Our sedentary lifestyles and ultra-processed foods are making us overweight and sick. Our thermoneutral environments are making us soft. Our digital world is leaving us physically disconnected. Clearly, something is wrong with modern life. The solution? Embrace discomfort. This book explores the science behind counting your steps, cold showers, intermittent fasting, 'digital sunsets', and much, much more - and how it can improve your physical and mental health. Backed by powerful research, Death by Comfort is a fascinating and entertaining exploration of what we need to do in order to survive and thrive in the modern world.
