Changing Memory
I don’t know about you, but I find that many people in their middle years seem to enjoy nothing better than living in the past. Their retrograde memory takes them through a rosy nostalgic distortion of the good old days, or at least what they consider to have been the good old days. To them, everything was better in nineteen-forgotten. Somehow crime did not exist, family life was perfect, people were more polite, and so on.
And then there are those with a selective memory. They remember only those things they want to remember. For some it’s some past hurt they have nurtured for decades because they hope to, some day, be vindicated. What’s the use? As far as I am concerned, a selective memory can be put to better use by rejoicing in reliving happy events, while throwing the hard facts of pain and heartbreak out the window. After all, do we really need to overload our memory bank with what is best left forgotten?
Someone said that a clear conscience is usually the sign of a bad memory. While it may have been said in jest, there is some truth to that statement. As the years pile on, happy are those who disregard the less-than-perfect aspects of the past to concentrate on the present. After all, we cannot go back to change history, and ruing what we may have done and might do differently today is a waste of precious energy. For me, there is much too much living on which to concentrate at this very moment.

Technology’s Wonder
I don’t know about you, but I’m always impressed when I read about some new technological discoveries. And when you think about it, the inventions we have seen since the dawn of the century are not only amazing but coming along so rapidly they are dizzying.
Technology keeps on keeping on. New advances now making full use of the brain are the wonder of our age as they help the disabled. Case in point, the theoretical physicist Stephen Hawking, who has suffered from ALS for decades, has been able to continue his work despite his ever-increasing physical limitations. At one point, keyboards were adapted to obey his voice commands, but these days Hawking writes using his brain. A chip in his eyeglasses makes it possible for him to pick up radio waves from his mind and transfer them to his laptop so he can type mentally. Amazing or what?
And other disabled people who have a chip inserted in the brain and then connected to a laptop are able to mentally operate a wheelchair and household appliances, surf the net, write e-mails, even if they are totally paralyzed. The implanted chip is a sort of brain pacemaker about the size of a dime. What a welcome advance for so many paraplegics.
And for us who are no longer as young as we used to be and who may fear dementia in the future, technology may have a welcome solution. Researchers are working on the possibility of inserting a chip/pacemaker in the brain of people with memory problems that would upload memory. That technology is more than mind-boggling, and when you consider the number of seniors who suffer from dementia, it would amazingly redefine the golden years for an awful lot of people.
And who knows what other advances we’ll see in the next few years. Hoorah for our technological age!
