Years ago, a friend and I decided that your hair knows when you’re coming down with something. A really bad hair day just might mean there’s a bug in the system.
Thanks to Olympic pressures, a discovery has been made to detect infection early in athletes. The test, which involves the assistance of a luminescent mollusk, known as the piddock, will help coaches decide when to isolate a team member or to cut short the hard training sessions of a soon-to-be-ill competitor.
But I bet their hair looks like crap too.
