But the experiment was part of a bigger project that was so systematic and strictly controlled that the findings likely apply to other crops, too. “Giving preference to organic products because th

7、e you think theyre safer for the planet to grow things that way, or because you think pesticides are bad for you or your family, or you like that they come from a shorter distance away, thats great.”“But if you want to buy them because theyre more nutritious, youre confused, and we dont know if that

14、er.

She thinks that many learning disabilities that children have in primary school or high school can result from a lac

In this way, as they get older, children will begin to connect physical activity with higher learning,” says Margaret.Older people can develop the

17、ir brains as well. Cornell University studied a group of seniors who have a shortterm memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exe

18、rcise for older people should not be too simple. Learning some new skills or actions, such as with yoga or tai-chi helps to open up memory paths in the brain that may not have been used for a long time.
