to move their bodies. In a study published in the Journal of
Gerontology, it was found that in elderly individuals with poor
physical functioning, increasing their physical activity and
functioning conferred a 50% reduced risk of dementia during the 6.1
years of follow-up. Given the millions of elderly with poor physical
functioning who are institutionalized all over the country, the savings
to the medical system through this intervention would be astounding.
