Why is it that I feel down?

Twenty-two is the age we stop learning? Now that is a load of bunk. The human mind never ceases its learning process. If that were the case, then I am screwed because I am a twenty-four year old in college so therefore I must have stopped learning two years ago (which is unlikely). Now I will admit that maybe we do not learn as well as we used to when we were younger, but that is to be expected as our body and mind get older. Other than that, we never stop learning. Whoever told you that needs to be reeducated on how the human mind works.
