What we're asking and looking for is, are there a very few set of individuals who are actually walking around with the risk that normally would cause a disease, but something in them, something hidden in them is actually protective and keeping them from exhibiting those symptoms?
我们要找的是， 只有很少的一组个体 那些没有发病的， 但事实上有着能引起疾病的危险因子 在他们体内有某些东西，有某些东西藏在里面 事实上起着保护作用 使他们免于出现那些症状？
