I have had them since forever, and told they were genetic too.
Cow's milk eh? Milk is like my number one body import. I have it with everything and I love it. How can I have cereal without milk? Ahhhh! That almost seems unbarable.
Don't worry, I AM willing to try it, but that's like a total life style change. I'm almost hoping it wont work so I'd still be able to drink milk
