Since there is limited evidence that these programs bring cognitive benefits, be skeptical of these claims and choose the ones that you enjoy.

The American Psychiatric Association has recently added prolonged grief disorder to its official list of classified mental disorders. Someone may develop this disorder when someone close has died within the past 12 months. The person may experience intense longing for the deceased or preoccupation with thoughts about him or her. These feelings occur most of the day and nearly every day for at least a month. Recognizing the signs and seeking out help with talk therapy are the best approaches to help prevent it from evolving to depression.
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. This makes it harder for men to build and maintain muscle as they age. One solution is a well-designed weight training program. Workouts should focus on all major muscles, but men should pay extra attention to leg muscles, which they rely on more for everyday movements as they age.
Dietary fat can both help and hurt heart health, depending on the source. Eating adequate amounts of the “good” fats—monounsaturated and polyunsaturated—can help reduce cholesterol levels and lower blood pressure. “Bad” saturated fat found in many processed foods can have the opposite effect.
