Waves,

I wish you can explain this to hubby for me.

I have explained the "toxin" thing to hubby a million times but he does not "get" it -- and this from a guy with a big interest in chemistry and other sciences.

I have given up.
Lately I do a broken record kind of thing:
"If you want to risk it, I am prepared to call the ambulance for you."
I repeat it several times before making something else for myself to eat.
