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?
O que estamos a perguntar e a procurar é: haverá um conjunto  muito pequeno de indivíduos que, de facto, correm um risco que, normalmente, provocaria uma doença mas que têm qualquer coisa,  qualquer coisa oculta, que os protege e impede que eles manifestem  esses sintomas?
