What are suppose to happen when one person grows older? Becomes more mature? Has more knowledge? Able to control emotions? I don’t seem achieve any of those.

I think most of doctors have nothing better to do than come up with all these new diseases. A lot of questionnaires available for people to do by themselves, and at the end of the questionnaires people tend to find out they are either physically or mentally ill. Seems like people in old ages were more healthier than now, even though they lived shorter lives.
