THE PROCESS OF AGING
Our neurons are non-regenerative. That means they do not divide to reproduce more of its kind. Once they die, they cant be replaced with another one. As we age, these brain cells of ours start to reduce in size and in number. This reduces our ability to call to mind some things that we have learned, including those in school, and even those details when we were younger.
A neurotransmitter called acetylcholine also declines as we age. This neurotransmitter is directly involved in memory and conveying of messages from a cell to another one. Moreover, because of the stresses that we have, the hippocampus, our memory bank, diminish in function.
