Go ahead. Pull all those bottles out from under your sink and have a look. Here is what all those warning labels are really trying to tell you:

Danger! A taste to a teaspoon could kill you. 

Warning! A teaspoon to an ounce could kill you. 

Caution! An ounce to a pint could kill you. 

These estimates are based on a 180 pound adult male. Small children and the elderly may be harmed by even lesser amounts.
