PHILADELPHIA (CBS) - As we get older there are certain things that we can’t do as well as we did when we were younger. For instance, most of us are less flexible, lose a bit of that jumping ability and have troubles with near vision and reading in a darker environment. All of these things are to be expected and although we battle hard to not give in to age, it is part of the process.

But one thing that is particularly frightening is when the memory starts to fail. Many people see this as a path to Alzheimer’s and other forms of dementia. However little changes in memory are as normal as not jumping as high or running as fast. It is very common to forget where you may have left the keys or struggle to think of someone’s name.

This is dramatically different than not knowing how to get home or forgetting entire conversations that may have happened a short time ago.
