If people don't mind saying, I was wondering what people here's birth order and family size is? I was curious, trying to figure out what could possibly cause emet... I'm interested in what causes certain people to feel certain things...I'm a first born, and I have one younger sister, and most of the times I remember something really graphic happening with v* when I was younger involved my sister getting sick... I was wondering if first borns are more likely to be emet, because they see their younger siblings get sick more often (because the younger ones may be less likely to get to a bathroom), or maybe younger siblings are more likely to be emet, because they see their older family members suffering from sickness... and maybe big families are less likely to have emets in them, because of more exposure opportunities, or those may make people more likely to be emet? I'm just curious if these things have any affect... any opinions?
