Health
Several environmental factors related to health can lead to significant cognitive impairment, particularly if they occur during pregnancy and childhood when the brain is growing and the blood–brain barrier is less effective. Developed nations have implemented several health policies regarding nutrients and toxins known to influence cognitive function. These include laws requiring fortification of certain food products and laws establishing safe levels of pollutants (e.g. lead, mercury, and organochlorides). Comprehensive policy recommendations targeting reduction of cognitive impairment in children have been proposed.

Famous quotes containing the word health:
“Pardon me, you are not engaged to any one. When you do become engaged to some one, I, or your father, should his health permit him, will inform you of the fact. An engagement should come on a young girl as a surprise, pleasant or unpleasant, as the case may be. It is hardly a matter that she could be allowed to arrange for herself.”
—Oscar Wilde (1854–1900)
“No one ever promised me it would be easy and it’s not. But I also get many rewards from seeing my children grow, make strong decisions for themselves, and set out on their own as independent, strong, likeable human beings. And I like who I am becoming, too. Having teenagers has made me more human, more flexible, more humble, more questioning—and, finally it’s given me a better sense of humor!”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 4 (1978)
“Youth no less becomes
The light and careless livery that it wears
Than settled age his sables and his weeds,
Importing health and graveness.”
—William Shakespeare (1564–1616)
