Science has shown that when people multitask, they become more easily distracted and less productive, score lower on tests for recalling information, and make more errors. Older adults especially struggle with multitasking because aging brains have more trouble blocking distractions. The solution is to monotask by focusing on only one job until it’s completed. Methods for monotasking include prioritizing tasks, blocking distractions, and working in intervals.

Recent guidelines suggest a blood pressure reading of less than 120/80 mm Hg as normal. But the ideal number for individuals depends on their individual goals and whether they also have a chronic condition, such as heart disease or kidney disease.

Sugar is a carbohydrate that provides the body with energy and has an important role in nutrition. It is found in many healthy whole foods, but it is also abundant in unhealthy processed foods. The problem many people have with sugar is that they consume too much of the refined kind added to many processed food products, and not enough of the natural kind in fruits, vegetables, and grains.

In addition to major healthy lifestyle habits, such as exercising and eating a healthy diet, it’s important to practice lots of little healthy habits throughout the day. Some should be observed every 30 minutes, such as taking a quick activity break and drinking a little water. Other habits, such as having a healthy snack or using eye drops, can be done every few hours. And some healthy habits help if practiced even just once a day, such as learning something new, chatting with someone outside of the household, or meditating.

Heart failure symptoms, such as being tired or out of breath, gaining weight, or having swollen ankles, can be overlooked and attributed to other causes. As a result, heart failure is not usually diagnosed until months or years later, when a person is hospitalized for it. By that point, the risk for dying from heart failure has already risen significantly, sometimes higher than the risk of death from cancer. Someone who has potential heart failure symptoms should talk to a doctor, especially if symptoms are new and if the person has diabetes, heart disease, high blood pressure, obesity, or an unhealthy lifestyle.

There’s no one sound unique to a particular shoulder problem. That makes it hard to know what various shoulder noises are telling you. Possibilities include arthritis; bone breaks; rotator cuff tears; gas bubbles, loose parts, or bone spurs in the shoulder joint; neck problems; and bursitis. It’s advisable to investigate shoulder noises if they happen, along with shoulder pain, weakness, or limited movement, or if the sound followed a shoulder injury. It’s also smart (though not urgent) to ask a doctor about shoulder sounds that aren’t accompanied by other symptoms.

There are many choices for lenses to replace a cataract. Examples include lenses that allow a person to see clearly at a single distance, or at several distances. Some types can correct astigmatism. When deciding which lens to choose for cataract surgery, people should consider costs, daily vision needs, existing vision problems, and pros and cons; for example, some lenses have more vision range than others, but also have risks of glare at night; some lenses still require a person to use glasses for up-close or distance vision.
