If possible, everyone should prepare for the possibility of needing support services or long-term care in older age, even if it's not yet needed. Ways to prepare include designating a health care proxy and power of attorney; writing advance directives for health care preferences; investigating potential housing options (such as assisted living facilities) and support services (such as a health aide) well in advance; downsizing belongings, including one's home; and meeting with a financial planner to figure out how to tackle caregiving expenses.

In a 2025 study of more than 221,000 people followed for more than 30 years, scientists calculated that swapping about a tablespoon of butter per day for about two teaspoons of olive, soybean, or canola oil was tied to a 17% reduction in premature death.

The protein collagen supports skin, hair, nail, bone, joint, and muscle health. As people age, natural collagen production drops. Some early research suggests collagen supplements offer benefits, but people should ask their doctor about the pros and cons.

Daily morning exposure to blue-enriched light can improve sleep quality and increase activity levels in older adults, according to a 2025 study. Researchers believe morning blue light "wakes up" the brain, which increases alertness and synchronizes the sleep-wake cycle.

In the last few years, the prescribing rate for zolpidem, a popular sleeping pill, has been declining in favor of the "off-label" use of an antidepressant called trazodone, which is known for its ability to make people drowsy. But doctors are concerned that trazodone hasn't been well studied for insomnia, it is not FDA-approved to treat the condition, and there are sparse data showing that it is safe or that it works for patients with insomnia. Experts advise choosing medications based on a patient's specific needs, not a trend.

Super-agers are people who reach their 80s, 90s, or beyond with the memory capacity of someone at least three decades younger. As people get older, certain brain regions shrink, slowing brain functions. But super-agers retain more brain volume in areas linked to memory and movement, and their brains shrink more slowly over time. Women are more likely to be super-agers because they live, on average, longer than men. Genetics also appear to play a significant role in achieving super-ager status.

Dancing is a popular leisure activity. Evidence suggests dance boasts all the same benefits as other forms of consistent aerobic exercise: lowering blood pressure, building muscle and bone, increasing aerobic capacity, reducing anxiety, and improving depression symptoms. Dance can also counter loneliness and isolation and be easier to stick with than exercise that's more repetitive. People who want to try dance can frame it as a hobby instead of exercise, take a group class, and modify dance movements to accommodate pain or limited mobility.
