I first encountered Tenner's work 10 years ago, when I was studying for my undergraduate. In his book, 'Why Things Bite Back: Technology and the Revenge of Unintended Consequences', he considers a number of cases related to sport and technology, which informed my own work. I have been reminded of his work again through the Hastings Center's Bioethics Forum, for which he writes. I will next visit the Hastings Center in May for a project meeting.
