Men tend to lose as much as 3% to 5% of their muscle mass per decade after age 30, and the muscle-building hormone testosterone gradually declines after age 40.

A test called a coronary artery calcium (CAC) scan uses a special type of x-ray to look for plaque in the arteries of the heart, which raises the risk of heart-related problems. While CAC scans can be valuable for detecting people at higher risk of heart problems from plaque buildup, this test isn't right for everyone. It's typically most useful for people who don't yet have symptoms of heart disease, but who do have some risk factors. Determining how much plaque is in the arteries can help guide decision making about preventive strategies. The test is less useful for people at very low or very high risk for heart disease.
