Exoskeleton that allows humans to work and play for longer

Would you put on an exoskeleton that meant you could run for an entire day without getting tired? What about one that would allow you to stay on your feet longer at work? The technology to give people superhuman strength is currently being developed but the ethical questions about whether we should be developing it and in what circumstances it should be used, are only just beginning to be asked. An exoskeleton, as the name suggests, is an external frame that can be worn to support the body, either to help a person overcome an injury or to enhance their biological capacities. Powered by a system of electric motors, the frame gives limbs extra movement, strength and endurance.
