Never before has technology had a greater influence on the body. Our physical selves can increasingly be monitored and, when necessary, improved. And the relation between the human body and its surroundings has never been subjected to so much control. Why not freeze your eggs until you’ve had a successful career and then have children? Or take a chemical test to determine whether you’re really in love? And instead of following a diet, use intelligent cutlery that knows precisely what a daily portion of healthy food is. We are constantly faced with the choice: buy or boycott, opt-in or opt-out.
