Age is irrelevant.
“Old men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight. They become accustomed to the more plodding varieties of reason, and because this is more than made up by the accumulation of experience, old men think themselves wiser than the young.”
Age is simply the accumulation of information. Some people accumulate more, some less. You can have more intelligent younger generations that the older ones. Keep your mind sharp, and keep studying. People tend to believe they should stop learning when they age, because they are already “wise”. Younger individuals have more potential than older individuals to learn. You’ll learn what that means, and more. ^.-
