Virtually everyone carries the bacteria Clostridioides difficile, or C. diff. But half a million Americans a year develop a serious C. diff infection due to a gut microbiome imbalance. It disproportionately strikes people in hospitals and nursing homes, and can recur repeatedly.

Mnemonics are techniques for recalling information. One type of mnemonic is called "look, snap, connect," which uses visualization, word association, and storytelling to help solidify a memory so people can recall it later.

According to a 2023 study, people who consumed 25% or more of their daily calories from added sugars had an 88% higher risk of developing kidney stones compared with those who kept their added sugar intake to less than 5% of their daily calories.

Older couples who have fallen into a sexual rut can try to spice things up—and perhaps strengthen your relationship in the process—by reading erotica that caters specifically to older adults. Reading and listening to erotic stories as a couple lets both parties explore fantasies in a safe environment and create an exciting atmosphere by encouraging couples to venture outside their comfort zone. Besides reading aloud to each other, couples can read on their own and share the experience or listen to erotic audiobooks and podcasts together.

A 2023 study suggests using hearing aids may reduce the risk of cognitive decline, especially in older adults with the highest risk of developing severe cognitive impairment.

White spots on fingernails are common and have many possible causes. These include minor trauma to the fingers, wearing nail polish for prolonged periods, fungal infections, low iron levels, kidney disease, or liver cirrhosis.

In a 2023 study, among people age 50 or 60 who reported high rates of exercise, those who said they slept less than six hours per night had faster rates of cognitive decline over the next 10 years than those who said they got six to eight hours of sleep per night.

Having a sense of purpose is linked to important health benefits, such as longevity and sharp thinking skills. There are many ways to cultivate a sense of purpose. Ideas include thinking about one's strengths or skills and how to apply them; becoming a mentor; volunteering time to a worthy cause; reading Viktor Frankl's book Man's Search for Meaning; writing about lived experiences and sharing the information with family or friends; and thinking of longtime dreams and ways to achieve elements of them.

It's hard to get rid of sticky thoughts, which play repeatedly in the mind and cause distress. Strategies that can help include going for a walk, staying busy by scheduling activities, limiting worry time to one specific period of each day, and talking to family and friends. If sticky thoughts don't go away after a few weeks, it might be time to talk to a primary care doctor or a therapist. Treatment might involve cognitive behavioral therapy, which helps someone recognize sticky thoughts and redirect them in ways that are less negative and more manageable.

Some doctors feel it's unlikely that editing people's genes will help prevent them from getting Alzheimer's disease. It's not just because attempts to edit genes inside the cells of living animals are in their infancy. It's also because most cases of Alzheimer's disease occur in older adults, and those cases do not appear to be caused just by a few defective genes. Lifestyle—particularly exercise, diet, and the amount of high-quality sleep—affects the risk of developing Alzheimer's at least as much as genes.
