Kind of scary: that something even your parents have no control over can have a dramatic impact on your own life. I wonder if this can also help explain things like autism since there never seems to be any genetic link. Of course, if it is an epigenetic link (as is the case in the above report) it won’t show up as changed genes, but to my knowledge no one really has an effective way to measure the epigenome at present, let alone compare it as it changes over life and/or generations.
