As the years tick by on the calendar, there are a few things that are a certainty as we all get a little older.

Your kids grow up way too fast. They don't make things like they used to. None of the new shows are as good as the old ones. Music is more confusing nowadays than ever.

And a lot of the people you're used to in popular culture seem to be retiring or sadly, having their lives come to an end, seemingly more and more frequently.

Man... what a pity-party way to start an article. But in this case, it's just a job change and a desire to do something different that will usher 9News anchor Tom Green off into a new chapter of life.

Green has been on your TV in Denver for more than 40 years, after leaving ESPN to come here in 1982. But for him, the rigors of the 24/7/365 news cycle are no longer the bee's knees.

In a couple of weeks I will do my last newscasts at 9NEWS, and start on the next phase of my life. What that is, I don’t really know yet. I have a couple of cool projects that I’ve been working toward, but I’m not sure how much (or even if) I plan to work anymore. My guess is I will, but not in a 24/7/365 news environment like I have been doing. It’s been quite a ride. -Tom Green, via 9News

For Green, there's a next chapter ahead. For us, another staple of our lives will be missing from TV in the imminent future, the same way we felt when David Letterman retired or learned that Gene Hackman had passed away.
