Take a quick look at this You Tube video.
If you are over 45 years old you will think it is stating the obvious. If you are over 30, it may give you pause to reconsider how you spend your life.

Now I understand why my father used to despair over me during my younger years. He would observe what my mates and I spent our time on and how we lived our lives and consider that we would miss out on so much that he enjoyed when he was growing up.
I remember doing exactly the same thing over my own children.
