Actor Carl Reiner — at 95 years old — just wrote an op-ed in The New York Times directed at Justice Anthony Kennedy:

I would like to start with congratulatory wishes on your forthcoming 81st birthday.

As someone who has almost a decade and a half on you, I can tell you this: It may well be that the best part of your career has just begun. As a nonagenarian who has just completed the most prolific, productive five years of my life, I feel it incumbent upon me to urge a hearty octogenarian such as yourself not to put your feet up on the ottoman just yet. You have important and fulfilling work ahead of you.

When I turned 81, I had finished “Oceans Eleven” and was gearing up for “Oceans Twelve” while also writing another book, which led me to a cross-country book tour.

Just a reminder that most of us aren’t trying hard enough.
