Sepsis causes or contributes to an estimated 20% of all deaths worldwide. The condition begins with an infection that spreads and over activates the immune system, which releases damaging inflammatory chemicals that lead to organ failure. Any infection can trigger sepsis, but those that begin in the lungs, urinary tract, gastrointestinal tract, or skin are more likely to do so. Older people are more susceptible to sepsis. The condition may be avoided by stopping bacterial or viral infections from occurring or worsening.

As people age, their teeth and gums can change. Examples include receding gums, shifting teeth, changing tooth color, and reduced tooth pain. These changes can be due to the wear and tear that comes with age, the development of disease, or natural changes in the components of tooth material. Dentists stress the importance of brushing and flossing teeth daily, getting teeth professionally cleaned twice a year, and talking to a dentist about solutions to dental problems.

Many people worry about occasional memory lapses that occur as they get older. To cope, it helps to talk to a doctor and also reduce stress by following healthy lifestyle habits, such as exercising, getting enough sleep, eating a healthy diet, and meditating. Using strategies to help retain information is also important. Examples include placing keys in a designated spot, taking medication at the same time each day, and using notebooks-not just memory-to organize and store information for fast retrieval.

The approach to certain blood tests appears to be shifting. Doctors might stop ordering routine vitamin D screenings for healthy people younger than 75; they might order a one-time combination of lipoprotein(a), C-reactive protein, and LDL (bad) cholesterol tests as a way to predict future heart problems; and they might rely less on standard ranges designated as "normal" in a complete blood count (CBC) test, and instead focus more on comparing someone's latest CBC results to previous CBC tests.

In a 2024 review of 116 randomized, controlled trials including almost 7,000 people (average age 46) who were overweight or obese, as little as 30 minutes of aerobic exercise per week was linked to reduced body weight, waist size, and body fat over eight weeks.

In a 2025 study of 40,000 coffee drinkers followed for a decade, those who drank coffee in the morning were 16% less likely to die during the study period, compared to those who didn't drink coffee. The benefit didn't appear among those who drank coffee throughout the day.
