Age that matters

Dear Friends,

I certainly don't consider myself "old." To be honest, I am not sure what age qualifies as old today. I think that being old is more connected to a mindset. That said, I am certainly not in my twenties any longer, and my body occasionally reminds me that it is not as flexible as it once was. Getting older is a fact of life. No matter how we much we would like to avoid it, the clock will continue to tick and we will grow older. It's inevitable!

Personally, I hope that I will age gracefully, but I do hope I can keep my mind snappy and youthful.

Fortunately, I've got some positive news about staying young mentally. Apparently our brains don't age the same way our bodies do. In a Harvard study, researchers compared the differences in brain activity between younger and older subjects focusing on the firing between the front and back of the brain in each group. This front and back mechanism is called the "default network" and is activated when we need to use our memory. As you would imagine, the twenty-year- olds had the best responses when it came to this part of the study. The older subjects tended to have a weaker connection in their "default network."

Yet surprisingly, nearly half of the older adults maintained brain activity that was similar to the twenty-year-olds. I was very pleased with this news, friends. Scientists attribute this younger, fit mind in an older body to good old-fashioned exercise, meaning cognitive exercise in this case. And they provided it by putting a group of 75-year-olds through several months of rigorous mind exercise. And after that, the subjects exhibited the memory abilities of people many years, sometimes even decades, younger.

So, in a nutshell, the more you exercise your brain, the better it will work and the longer it will last. According to researchers, when we "workout" our brains through mental exercises, we are actually building cortical tissue that helps our brains last longer. Unlike fat cells, the more brain cells we have, the better. That's because those extra brain cells are like insurance for the mind. If we are able to store up and maintain a good number of brain cells, then this reserve will help us to cope with the natural loss of cells that occurs with age.

Mental exercises that help build brain cells include reading, doing math, and playing games that call for strategy and matching. Your computer is a good source for such material. There are loads of brain boosting workouts available to play online, to load onto your pc.

Friends, you might want to consider adding brain exercises to your daily physical regime. Many of us are particularly fond of Sudoku, in addition to regular physical exercise of brisk walking and yoga. It never hurts to start early when it comes to taking
