Interesting in the first post that it mentions 95% of us have this chemical in our urine, but not 95% of us will get cancer.
We use nuk bottles here and they have a 7 on them, I thought about glass but have heard you can't microwave sterilise the bottles so flagged that idea and thought I would probably drop the bottle on the granite bench and break it too. I am not going to worry too much, man breathing in the chch winter air would probably give you cancer faster anyway.
God even sleep gives you cancer these days.
