I am not condoning this, but there have been cases reported somewhere in my own family members, especially those from back in grandma or great grandma's day: the pregnant women eating starch is one of those; and yes, she had her babies, and yes she lived to be a ripe old age. Another case was the part where a male cousin used to eat clay; he did get sick, but lived. It is a very unhealthy thing, however. Joseph
