Scientists wonder if gut microbes might influence behavior in animals, including humans. Some studies suggest a link. For example, a 2022 study suggested that gut microbes can influence an animal's motivation to exercise. Scientists speculate that the same might be true in humans. Other studies have found that a parasite called Toxoplasma gondii is tied to risky behavior in lab mice and risk-taking behaviors in humans. Scientists now even consider it conceivable that gut microbes might influence things like human intelligence, attitudes, empathy, and more, although the idea has yet to be proved.

In the last 10 years, an average of four drug recalls a day have occurred in the US. Drug recalls happen for a number of different reasons, and while they are common, most are not for dangerous or life-threatening issues.

The modernization of standard home medical devices has made monitoring health easier than ever. These gadgets include thermometers, scales, blood pressure monitors, and pulse oximeters. Gadget features that are especially helpful for older adults are easy operation and large, lighted readouts.

There’s no evidence that maintaining a healthy lifestyle will suddenly boost the immune system. However, it’s clear that healthy lifestyle habits contribute to overall health, supporting the body’s ability to fight infections instead of creating new problems.

Many COVID-19 symptoms — such as fever, cough, or muscle aches — overlap with the symptoms of other respiratory conditions, such as influenza, a common cold, or asthma. But there are differences among the conditions. For example, a bout of the flu or a cold will not cause shortness of breath the way COVID-19 will. And while asthma can cause shortness of breath, it won't cause a fever or body aches the way COVID-19 will. A person who's experiencing concerning symptoms of respiratory illness should report them to a doctor.

People who walk for their primary form of exercise, or even just for recreation, need to make sure they stay in good walking shape to avoid injuries and improve their endurance.
