Staying Well: Start young to stay young

Physical decline may actually begin in the 20s, but there are things every person can do to feel young.

A study by Duke University found that some types of physical decline happen later than others. Hearing can begin to decline around age 25. On the other hand, lower body muscle performance decline may not be detectable until you are in your 50s, according to the Wall Street Journal.

Everyone wants to stay young, and perhaps the best way to do that is to take action. Donald Stuss, Toronto neuropsychologist, found that physical activity brings more blood, nutrients, and oxygen to the brain, which is thought to help delay brain decline.

Although exercise is important, it's also important to take a break between sessions, says John Higgins, MD, associate professor of medicine at The University of Texas Health Science Center. Never taking a day off can impede your body's healing from the tiny tears caused by exercises.

If you stop eating before you're entirely full, that may help as well. Researchers at St. Louis University have found that eating fewer calories can help metabolism.

Another diet-related tip: ensure that your diet includes plenty of foods with antioxidants that break down free radicals and protect the brain. Foods high in antioxidants include fresh fruits, vegetables, beans, spices and whole grains.

Standing with proper posture can have an immense impact on how you feel, and how your spine is affected, which could cause problems later in life. Tom Holland, exercise physiologist and author of Beat the Gym, notes that exercises that require pulling and reverse movements can help to avoid spinal problems later on.
