As you say, just you feel old but your age 40 ,it is not old, so it is just mental feeling not physical issue if you think positively everything will be positive then you will be a real young guy.
I am 70 but do what I do as normal. Numbers mean nothing, it's mental attitude. That's all. Never stopped doing what I do.
The issue is changes in the world that happen faster than our minds can adjust. A few days ago I went to our local Target store and struggled yet again with a shopping cart that locked up as I returned to my vehicle. So I complained to a store manager and was told that he carts have a device that DELIBERATELY disables the cart a certain distance from the store to prevent theft of the cart! WTF.
When I last posted on this thread, three years ago, I was still young. I got old two years ago, when I got pneumonia. Ambulance ride, three weeks in hospital, and now my lungs are permanently scarred. I like to think I am still young mentally, though I might be kidding myself. But getting old physically can happen suddenly.
I have been to stores that do that with shopping carts. They claim it is to prevent Homeless people from stealing them.
Yes you are right, the thinks have been changed because of the technology, but it doesn't mean if we don't know how to deal with the technology, we are old! It takes time to learn the new things but , still we can lean more or less to solve our primary needs, and our weaknesses is not related to our ages, it mostly related to the level of our education.
A friend of mine called me today to wish happy holidays. Our convo turned towards age and health which brought up a mutual friend of our who was a vibrant active person not just a couple of years ago is now confined to the house. At any age ones health can turn for the worse but as we get older the odds increase tenfold.
