BY LISA MARSHALL mMany of us hit midlife with trepidation—certain that it’s all downhill from there, at least from
a biological standpoint. And yes,
stats seem to support that belief:
Two-thirds of people experience
some mental decline by age 40,
likely due to age-related thinning
of neurons and synaptic connections,
and one in eight people age 65
and older will eventually develop
Alzheimer’s disease. But it doesn’t
have to be that way: Your brain is not
destined to break down as you age.
