Video: Secrets to Protect Your Aging Brain

Just a few weeks after my 64^th birthday, I discovered an interesting video. The timing couldn’t have been better.

The topic: maintaining brain health as we age. This video has tips, based on research, for preserving or improving memory and reducing brain inflammation, which is a culprit in cognitive decline.

“Daily lifestyle habits have a much bigger impact on your longevity than your genes,” Dr. Gary Small, former director of UCLA’s Semel Institute for Neuroscience and Human Behavior, explains in the video.

Did you know that Indian people have less dementia, because they eat so much turmeric in their curries? Or that a brisk 20-minute walk every day lowers the risk of Alzheimer’s disease? Most people know that yoga, meditation and tai-chi reduce stress, but did you know that stress is, according to Dr. Small, “the enemy of healthy aging”?

His message is encouraging: there are things you can control to help you live a good life in old age. “It’s easier to protect a healthy brain than to repair the damage,” he said. …Learn More

Walk? Yes! But Not 10,000 Steps a Day

A few of my friends who’ve recently retired decided to start walking more, sometimes for an hour or more a day.

Becoming sedentary seems to be a danger in retirement, when life can slow down, and medical research has documented the myriad health benefits of physical activity. To enjoy the benefits from walking – weight loss, heart health, more independence in old age, and even a longer life – medical experts and fitness gurus often recommend that people shoot for 10,000 steps per day.

But what’s the point of a goal if it’s unrealistic? A Centers for Disease Control study that gave middle-aged people a pedometer to record their activity found that “the 10,000-step recommendation for daily exercise was considered too difficult to achieve.”

Here’s new information that should take some of the pressure off: walking about half as many steps still has substantial health benefits.

I. Min Lee at Brigham and Women’s Hospital in Boston tracked 17,000 older women – average age 72 – to determine whether walking regularly would increase their life spans. It turns out that the women’s death rate declined by 40 percent when they walked just 4,400 steps a day.

Walking more than 4,400 steps is even better – but only up to a point. For every 1,000 additional steps beyond 4,400, the mortality rate declined, but the benefits stopped at around 7,500 steps per day, said the study, published in the May issue of the Journal of the American Medical Association.

More good news in the study for retirees is that it’s not necessary to walk vigorously to enjoy the health benefits. …Learn More
