Many songs from the 60s, 70s, and after and even before seem to be eternal in that we can sing the lyrics and the tune decades later. Even some good TV shows and movies have an almost ever-lasting feel to them....as they are shown on TV as reruns and we purchase DVDs to have in our collection for viewing again and again.

But sports is different, and that difference is what makes sports ultimately kind of stupid. There is little to no reason to want to care about saving memories of some game, or even some season, from years or decades ago. No TV channel will ever show, or DVD will ever sell, the "complete game" of a long-gone game from year's ago because, unlike enduring songs and many TV shows, "sports" is fleeting. Ultimately, once the season is over, interest in "what was" fades.....and we return to those things that are much more entertaining and enjoyable.....such as music, TV shows, and even movies from decades ago when we lost any interest in the football games from that time.
