“Anyone who stops learning is old, whether at twenty or eighty.
Anyone who keeps learning stays young.”
When we are children there are good evolutionary reasons for being credulous but when we attain adulthood we begin to come to our own conclusions about life. And we should take full advantage of our innate capability to experience, to reason and to develop our knowledge in a way that shapes our values and stimulates our minds. And as we get older we will know that it was time well spent. Because of lifelong learning we may become old of body but we will be young of mind.
