Secret of Eternal Youth

The secret to staying young is to not have friends your own age.

And what I mean by that is have so many friends who are so much younger than you. They bring a whole new worldview to you. But you can't just be friends with these younger people. You must listen to them. You must appreciate what they have to offer and if you cannot do that then you cannot be their friend. And if you cannot be their friend, then you were only going to be friends with those who are your own age or older and is a result you will lose any opportunity if remaining youthful.
