This is strange . . . but probably a pretty useful trick if you're going swimming in a place that's known for jellyfish. If you want to avoid getting stung, try putting on PANTYHOSE.
Most jellyfish have very short stingers that can't even get through the mesh of the pantyhose. And ones with longer stingers usually don't sting unless they're triggered by contact with skin . . . and the pantyhose prevent that too.
So what about our upper body? I guess a gurdle would suffice...sure will look funny...OR start a new trend!
