An Explanation of the phrase "The Tarzan Years"

Well, it's kind of silly, I know, but I think of myself as Tarzan swinging through the jungle by vines, you see. The current vine holding me up is a drug called Crixivan. But like all AIDS medications, eventually the virus will mutate and become immune to Crixivan.

At that point, all I can hope for is that a new drug will come along so I can reach out and grab it and continue "swinging."

And, no, it's not the TARZANA years. I've never even been to Tarzana.
