To the editor:
New research boots the "use it or lose it" theory about brain power and staying mentally sharp. People who delay retirement have less risk of developing Alzheimer's disease or other types of dementia. It is the largest study to look at this and the conclusions make sense.
Working tends to keep people physically active, socially connected and mentally challenged - things known to help prevent mental decline. For each additional year of work, the risk of dementia is reduced 3.2 percent.
People should work as long as they want to: it has health benefits and for the simple fact that delaying retirement may help the risk of mental decline. Staying cognitively and socially active and maintaining our place in the workforce may actually improve the golden years.
