Scientists from the UK have proved that human memory depends on the number of teeth. The fewer the teeth, the worse indicators of intelligence. In total the study involved 3 thousands of older people. They offered to go visit your dentist and special IQ test.
Less teeth, the worse the memory. The absence of teeth reduces the process of remembering information by 10%, say scientists.
On the causes of the phenomenon of experts do not undertake to judge. It is likely that the loss of teeth reflects the natural process of aging, and the deterioration of memory and intellect are common in the elderly.
