- Each person has about the same number of brain cells at birth as in adulthood, but those cells grow, reaching maximum size at about age six.
- A newborn’s brain triples its size in the first year of life (no wonder babies have such big heads!).
- The sense of touch is the first sense to develop in a fetus, with the lips and cheeks experiencing this sensation at eight weeks.
- Keep exercising your brain, because mental activity stimulates the creation of new neurons throughout your whole life.
