#Studies have shown that children who are breast fed display IQ's up to 10 points higher by the age of three.
#The right side of your brain controls the left side of your body, and the left side of your brain controls the right side of your body.
#Your brain weight accounts for about 2 percent of your body weight. But your brain uses 20 percent of your body's oxygen supply and 20 to 30 percent of your body's energy.

When preservatives, coloring, dyes and artificial flavors were removed from the cafeteria menu researchers found that 70,000 students performed two or more IQ grade levels higher than before.
#Even though there are huge differences in weekly earnings between people of various educations levels there are also great discrepancies between people with comparable schooling and higher intellectual capabilities.
#IQ is not influenced by family size or birth order. There is some confusion on this
