"No athlete likes hitting \u201Cthe wall.\u201D You know, that point at which their energy level suddenly plummets, and they just can\u2019t go on. Using something that looks like a temporary tattoo, however, they may soon be able to receive a warning when they\u2019re approaching that threshold.\r\n"^^<http://www.w3.org/2001/XMLSchema#string>
