We'd have to go and have a pretty wide study, and we realized that actually one way to think of this is, let us look at adults who are over 40 years of age, and let's make sure that we look at those who were healthy as kids.
Tam būtu jābūt vērienīgam pētījumam, un mēs sapratām, ka viens veids, kā to paveikt, ir pievērsties pieaugušajiem,  kas vecāki par 40 gadiem, un pārliecināties, ka pētām tikai tos, kuri bija veseli arī bērnībā.
