As men age, many factors affect their energy levels, such as declining muscle mass, unhealthy diet, poor sleep, and increased stress. Addressing these areas are some of the best ways to increase energy levels. Exercise, healthy eating, good sleep, and stress reduction can increase mood-boosting hormones, help the body produce more adenosine triphosphate (the energy-carrying molecules found in cells), and balance blood sugar levels to prevent sudden fatigue, among other benefits.

The American Heart Association added sleep to its list of factors for cardiovascular health. The others are a healthy diet; physical activity; low levels of nicotine exposure; and healthy levels of weight, cholesterol, blood sugar, and blood pressure.

People who meet the recommended physical activity guidelines may experience the same health benefits regardless of whether they spread the exercise out over the week or do it all in one or two days.

Left-handers make up only 10% of the population. Despite some common beliefs, science has yet to show that left-handers have any specific advantages or disadvantages over right-handed people in terms of physical abilities, cognitive health, or longevity.

Many apps support activities that promote emotional well-being. Happiness apps feature affirmations, meditations, or gratitude journals. Exercise apps track daily physical activity or provide workouts. Meditation apps guide users through various kinds of meditation, such as mindfulness or guided imagery. Sleep apps help people track how long they sleep, and offer instruction to improve sleep hygiene—such as going to sleep and waking up at the same time each day, and avoiding food and drinks at certain times.

Harvard Medical School has created a large department dedicated to developing and teaching young scientists about the emerging field of computational medicine. This field uses new mathematical techniques to make sense of the thousands of numbers generated in experiments measuring various molecules. Analyzing such "big data" was once unimaginable. Now, scientists have the tools to do it, and to compare tissue of people with and without a disease to find out which molecules are different.

An adequate supply of primary care physicians is essential for our health care system to function properly, but it's becoming more and more difficult to find one. Rates of burnout are high among PCPs, and many are considering cutting back their work hours or leaving altogether.

Reaching and maintaining a healthy weight is a major health issue. An analysis of data from multiple studies found that when weight management interventions were delivered in primary care settings, participants lost more weight and kept it off longer.

Cooking with gas stoves releases nitrogen dioxide and gas appliances introduce other toxic chemicals into homes, but people can take steps to protect their household and help improve outdoor air quality, too.
