Faster, higher, stronger - the Olympic motto that inspires the best athletes to push themselves to the limit. But what if we changed where those limits are? What if we allowed humans to not just rely on good genetics and intensive training, but also on chemical, medical and biomechanical enhancements? The team at The Enhanced Games are aiming to answer this question in a few weeks time in Las Vegas - see http://www.enhanced.com for details. Is this the future of sport? Or are we crossing a line we should not cross?

Maybe a more important question is what sorts of human enhancements might be valuable and useful in your life and work? And are there any legal and ethical limits you should be considering?
