Another instance of how difficult it is for us to change our minds about something! Floo...you are a great example.
What is there in this that should encourage us to change our minds? There are any number of things that have happened to this child, being kissed by an Argentinian is just one of them. Why should we attach special significance to this?
If you want to convince us that this is significant you need to have a number of sick children kissed by old Argentians, and another group not kissed by old Argentinians, and then a comparison of the comparative outcomes of the two groups.
Otherwise it's as likely that his particular dining table has miracle healing powers, or his highchair.
