AARP Celebrates Brad Pitt's 50th Birthday

He might need a fire extinguisher to put out all 50 candles on his birthday cake, but Brad Pitt, who celebrates the milestone on Wednesday, has something else remember this birthday by – he's now eligible to join AARP.

The organization, originally founded for retired people, is honoring PEOPLE's twice-named Sexiest Man Alive (1995 and 2000) with a special edition birthday cover of AARP The Magazine.

"Acclaimed Actor, Producer, Humanitarian, and Family Man, Mr. Pitt Joins the Club" reads a line on the mock cover.

In an interview with PEOPLE last December, the father of six talked about turning the big 5-0 and being conscious of getting older.

"I want to make sure I'm doing things of value – that mean something to me," he said. "Make sure I'm doing things I've always wanted to try. And make sure I'm not doing things I don't want to do. Because I'm very conscious of time; I know it's limited."

One person he won't be asking for advice – his pal George Clooney, who is 52.

"He's too old. We live different lives," Pitt laughed. "What can he tell me? Other than how to protect my liver!"

You're 50, Brad, so listen up to a few things you ought to know listen up to a few things you ought to know

DAVID THOMAS – 18 DECEMBER 2013

So, Brad, you're turning 50, huh? Welcome to the club. I suppose your old buddy George Clooney's given you a few tips about how to enter one's fifth decade with elegance and grace.

Let's be honest, though: George is different. That man's been getting ready for 50 all his life. He was born a silver fox. You, on the other hand, have always had that surfer-boy look. It's ironic, really, given that you were actually born -- and not to rub it in -- on December 18, 1963, in Shawnee, Oklahoma, roughly 1,400 miles from the beaches of California.

Your first name wasn't Brad, either. It was William.

But I digress. Must be a symptom of age, I suppose. You see, I'm only a month shy of my 55th birthday, so I'm pretty well equipped to let you know what to expect and how to cope with it all. Now let's get to the nitty-gritty with some helpful tips.
