A scientist in Tokyo just found out that eating ice cream shortly after you wake up can make you smarter. To come to this conclusion, one group of people ate ice cream for breakfast and another group ate a normal morning meal. The two groups then did the same series of mental exercises on a computer. The people who ate ice cream seemed to have a faster reaction time and processed information better. When he monitored their brain waves, he also found they were more alert and calmer than the other group. (Photo: School Plus)
