Weirdest CES health gadgets that detect breast cancer, measure body fat and turn you into a computer device

The annual CES Las Vegas show is a famous testing ground for some of the slightly wackier health tech ideas. This year's is no exception, with developers bringing forward a range of products that could change how many people live their lives. Many of these products are now in the final stages of development and being released if not already available on early access. But a number also remain largely conceptual prototypes, such as a mirror for scanning someone for body fat percentage, which its presenter said was still very much just an example of what they could do. It sounds like something out of a sci-fi movie, but developers have designed a computer mouse controlled entirely by your tongue.
