After age 50, the number of taste buds begins to decline, so it's natural for people to notice some changes in their sense of taste. But other conditions also can affect taste, such as nasal issues, certain medications, and conditions like dry mouth and acid reflux.

While an active life is a healthier one, there are times when people can benefit from embracing a slower pace, an approach commonly known as "slow living." Slow living isn't about doing less, but doing more with greater focus and purpose and at the right speed. The approach can help people lower stress, increase concentration and memory, and become more engaged in activities they enjoy.

A 2022 study found that doing any type of aerobic activity for the recommended amount of time each week was tied to a 13% lower risk for premature death from any cause, compared with not exercising.

Several types of programs can make driving safer for older drivers. A Car-Fit evaluation helps improve the way a driver fits in a vehicle. A driving refresher course helps drivers stay up to date on driving techniques, laws, and vehicle safety technology. A formal driving assessment evaluates a person's physical and mental health and driving ability on the road. Driver rehabilitation provides training for people to use adaptive driving equipment, practice driving in challenging conditions, and develop safe driving habits.

There are many misconceptions about dementia. One is that it's a disease. In fact, dementia is a general term describing thinking and memory skills that have deteriorated to the point of experiencing problems with daily activities. Another myth is that dementia is part of normal aging. It isn't; dementia is simply more common as people get older — just like heart disease, stroke, and cancer. Other common myths about dementia include the notions that it always appears as memory loss, it's always genetic, it causes the loss of all memories, and it's never reversible.

Scientists are studying two novel approaches to improve memory. One approach centers on molecules in the blood and spinal fluid that appear to help improve memory. So far, experiments have been limited to lab animals. Another approach involves exposing the brain to electrical currents. A study in humans, published online Aug. 22, 2022, by the journal Nature Neuroscience, found that electrical stimulation directed at specific areas of the brain improved both working memory and long-term memory for at least a month.

Life expectancy is one measure of the general health of a population. In the US, life expectancy had been climbing for more than a century — until the pandemic. After dropping in 2020, it dropped again in 2021, and some population groups fared worse than others.

Alzheimer's disease and other forms of dementia affect all the regions of the brain involved in driving, but whether or not a person should give up driving depends on the severity of the disease and the specific cognitive abilities that are impaired.

A 2022 study found that women under 55 experiencing heart attacks have different leading risk factors than men in this age group. For women, diabetes, depression, high blood pressure, and low household income are strong risk factors for heart attack.

A 2022 study found that low blood levels of vitamin D (under 25 nanomoles per liter) were linked with higher risks of dementia. People can boost vitamin D levels from diet, supplements, or sun exposure.
