My Greatest Fear

is losing my mental capacity.

Live Science says you can half your risk.

Staying mentally and physically active throughout life is the best way to keep the mind sharp and reduce the risks of developing dementia, two recent studies show.

One large group study found that staying mentally active reduces the risk of Alzheimer’s disease and other forms of dementia by nearly half by building and maintaining a reserve of stimulation.

“It is a case of ‘use it or lose it,'” said study leader Michael Valenzuela from the School of Psychiatry at the University of New South Wales in Australia. “If you increase your brain reserve over your lifetime, you seem to lessen the risk of Alzheimer’s and other neurodegenerative diseases.”

They have it under “delay dementia.” Since I plan to live to be 120, I want to delay it till I’m 121.
