This is a very hard question to answer, as in some nations it is customery to pierce the ears of small children even infants, i see many Hispanic Familes with infants who's ears are pierced, then I ask myaself, is it their custom, or why did they do it
If it is there custom, evertyone nation and poplution has ones different then say Americans
I am not intentialy picking out Hispanics, i just livei n an area where they are a good portion of the population and see them and it daily, on the other hand other asreas ofthe country i never see it at all
