Give the gift of IQ

Want to know one of the most un-sexy, yet effective types of foreign aid?  Providing iodized salt to the world's poor. 

Almost one-third of the world’s people don’t get enough iodine from food and water. The result in extreme cases is large goiters that swell their necks, or other obvious impairments such as dwarfism or cretinism. But far more common is mental slowness.

When a pregnant woman doesn’t have enough iodine in her body, her child may suffer irreversible brain damage and could have an I.Q. that is 10 to 15 points lower than it would otherwise be. An educated guess is that iodine deficiency results in a needless loss of more than 1 billion I.Q. points around the world.
