Now that I am "older" I find that older is a lot younger than it used to be. My Uncle Jimmie use to define older as "fifteen years older than you." That's pretty good. To a 10 year-old 25 is old. To a forty-year-old fifty five is over the hill. To a 70 year-old 85 is the top.
Now that I have reached some of those more exalted years, I find I still have the same joy I had as a child. I am as happy to see Christmas. I still enjoy and praise. What is it that growing up or growing old is supposed to change? The requirement to act your age is entirely too vague. According to some of the developmental psychology theorists, many people never reach the higher stages. Maturity is hard work. The people who reach 75 are viewed as being wise. They are expected to find contentment and live in a state of integrity.
For people who do not achieve this high level of maturity and functioning, bitterness and despair may be the result. At least this is the dichotomy Erik Erikson describes. Some people who get to be an advanced age do not measure up to the Erikson's stage development, but I still regard them with respect. It is not for me to make judgments about their stage development. Old people should be respected, especially if they are older than I am. My mother said so.
