Action stars are not supposed to grow old like the rest of us, and yet some aging actors like Sylvester Stallone are here to prove that’s a myth. They are also ready to demonstrate that you can be 60-something and still cut a formidable figure. Just a glance at one of their recent films tells you all that you need to know. Or haven’t you seen the latest Rambo installment, or Rocky (Balboa)? Also, keep in mind how well Harrison Ford held his own in the recently released Indiana Jones and the Crystal Skull.

One of the most powerful forces in Hollywood cinema back in the 1980s, Stallone hadn’t made a Rambo film for twenty years until he wrote, directed, and starred in the latest installment.

According to a February 2008 article in TIME, Stallone tells Joel Stein that acting with only eyes and biceps is harder than playing a fast-talking boxer. It is especially hard on a 61-year old body, which is one of the primary reasons Stallone wanted to do the film—to prove he could.

Although he does not subscribe to steroids, he admits to using HGH, which he says is nothing, and that “anyone who calls it a steroid is grossly misinformed.” He believes testosterone is important for a man’s well being as he gets older, and feels anyone over 40 should be taking it to improve quality of life. He feels so strongly in fact, he predicts it will be sold over-the-counter in the next ten years.
