Mind-bending puzzles aren't the only route to improving memory and reason. Activities that engage your emotions and senses may be even better.

In the midst of promotions for commercial brain training programs to ward off age-related cognitive decline, a few studies are beginning to indicate that simple pleasures may be even more productive. You may find that doing one of the following is an easier and more rewarding way to boost your brain than doing computer-based exercises.

1. Care for a dog

3.Play with a child

Despite new research, the answer is unclear. Use caution when taking any pain medication on a routine basis.

People with aching joints from arthritis—which affects nearly one in four adults—often rely on drugs known as NSAIDs to ease the pain of this often-debilitating condition. These popular medications also relieve headaches, cool fevers, and dampen inflammation. But with the exception of aspirin, most NSAIDs pose a risk to the cardiovascular system, notes Harvard professor Dr. Elliott Antman, a cardiologist at Brigham and Women's Hospital.

"Taking NSAIDs routinely over a long time period can raise the risk of blood clots, increase blood pressure, and accelerate cardiovascular disease," says Dr. Antman. While the danger is greatest in people with heart disease, it's also present in people without any signs of the disease.

Cocoa flavanols, which are plant-based nutrients found in cocoa beans, seem to have beneficial effects on risk factors for heart disease. 

Lifestyle habits such as not smoking, avoiding obesity, exercising, and following a healthy diet may cut a person’s risk of heart disease in half, even if they have genes that put them at a high risk of cardiovascular disease.

Q. I have read about diets that involve fasting for one day, followed by normal eating for the rest of the week. Are there any benefits to this kind of diet??

A. Most diets achieve weight loss through the same equation—a reduction in total daily calories consumed in relation to the calories needed to maintain your weight.

Vascular dementia is a less prevalent type of memory loss that nonetheless affects many older men.

While Alzheimer's disease continues to be the most recognized type of dementia, older men should also be mindful about the second most common: vascular dementia.

In vascular dementia, memory problems result from damage to large and small blood vessels in the brain. It develops when cholesterol-clogged blood vessels can't deliver enough oxygen to the brain. Small blockages deprive some brain cells of oxygen, which causes a series of small strokes that kill brain cells. This can lead to episodes of confusion, slurred speech, and problems thinking or remembering.

Participating in a medical study may benefit your health and perhaps that of millions of others.

If you've ever considered donating your body to science—or granting science a temporary loan—now's the time to do it. Researchers are always recruiting patients for studies of new treatments and preventive strategies for diseases ranging from Alzheimer's to zoster (shingles). In the simplest terms, these studies compare existing approaches to newer ones in similar groups of people and determine which is more effective.

"Clinical trials are the vehicle by which we transfer things that we think into things that we know or don't know," says Dr. Jeffrey Drazen, professor of medicine at Harvard Medical School and editor in chief of The New England Journal of Medicine.

You may be able to save time and money—and spare yourself frustration—by adopting a more minimal approach to preventing disease.

As the Shaker lyrics go, "'Tis the gift to be simple," and simplicity is a gift you might want to grant yourself in the new year. If so, you'll have some help from health experts. In the past few years, complicated advice for diet and exercise has given way to simpler, more sustainable guidelines, and the FDA has come down in favor of simple soap and water over antimicrobial cleaners to prevent infectious diseases.

If you've vowed to make positive changes in your lifestyle this year, you're likely to be more successful if you don't take on complex new regimens. "People can achieve remarkable changes in their lives one small step at a time," says Dr. Edward M. Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School and medical editor of the Harvard Special Health Report Simple Changes, Big Rewards (www.health.harvard.edu/change).
