The neuroscientists' gloom was based on their belief that aging causes a steady loss of neurons (brain cells) all over the brain. They ''knew'' the adult brain could not generate new neurons. Worst of all, scientists assumed that nothing could be done to boost the odds of having a healthy, aging brain.
Some mental skills decline with age...but wisdom and common sense may increase.
