Here are some of the latest reports, surveys, and studies related to retirement, including research into the benefits of strength training, scams targeting veterans, and 401(k) performance.

Turns out you're never too old to learn new tricks -- and you're never too old to benefit from a good workout.

In research published in the Lancet, the authors of The Influence of Prolonged Strength Training Upon Muscle and Fat in Healthy and Chronically Diseased Elderly Close to Retirement Age write in the abstract: Background: Physical and cognitive function declines with age, accelerating after the age of 60. Strength training over a few months improves physical function, but less is known about how long-term strength training affects physical and cognitive function. Therefore, we aimed to investigate the effect of 1-year strength training of two different intensities upon muscle mass, function, and cognition in retirement-age individuals.

The study participants, both healthy and those with chronic health problems, did strength training for a year. Changes in muscle power (primary outcome), strength and size, physical function, body composition, hippocampus volume and physical/mental well-being were analysed. (The hippocampus, according to the National Institutes of Health, is a complex brain structure embedded deep in the temporal lobe. It has a major role in learning and memory.)

In the findings, the researchers wrote that, essentially, participants were able to lose weight, gain strength, and had improved mental health.
