After the mid-50s, 70% of aging is controlled by lifestyle. Genes
tilt us in certain directions, but whether or not we follow depends to a large degree on choices we make. A
person may have a genetic disposition toward heart disease, for instance, but lifestyle and environment play a significant
role in whether s/he actually develops it. Things can be done to cut the risk of heart disease, frailty,
Alzheimer’s, and many other illnesses and disabilities. We can begin at any time to increase our
health and well-being, live longer and live better. The sooner we start, the greater the rewards.
But the rewards are great no matter when we start....
If you quit smoking,
circulation immediately improves and the lungs start repairing damage. After one smoke-free year, risk
of heart disease, stroke, lung disease and cancer falls.
If
you’re overweight, losing 5 - 10% of your body weight and eating a nutritional diet low in fats and sugars can lower
blood pressure, help prevent type 2 diabetes and slow the aging process.
You can build your brain by growing dendrites at any age. Ongoing mental stimulation
and learning lessen the risk of dementia.
Alzheimer’s Disease is the most common form of dementia and developing it is the number
one fear of aging people. The good news: Dementia is not an inevitable aspect of aging. In
Okinawa, Japan seniors have one-third less dementia than Americans. They also experience one fifth of the
heart disease, and one fourth of the breast and prostate cancer of Americans. I guess that’s why
so many live past 100.
There
are things we can do to reverse negative trends and greatly improve our quality of life. Exercise has a
major impact on physical, psychological and emotional well-being. With ongoing learning, we can build better
brains. With desire and commitment, we can live healthy, happy, fulfilling lives.
