has charlie sheen become his character?

a few weeks ago, my most recent article was published. in the article, i put forth a simple math formula:

location + time = character.

and since writing that article, i have often wondered in what other ways (besides abiding in God's word) this is true. 

i am wondering today if charlie sheen embodies this formula.

(in the interest of full disclosure: i have not read every article about charlie sheen over the last few weeks. i haven't even read lots of them…just enough to know that sheen seems to be self-destructing.)

sheen plays charlie harper on the sitcom "two and a half men." sheen's character is a womanizer. he drinks excessively. and, according to wikipedia, he lives a life of free-spirited debauchery. in fact, that same wikipedia article states that the character of charlie harper is loosely based on sheen himself.

sheen has played this character for 178 episodes, from 2003 until the present.

and i wonder…has sheen taken on the character of charlie harper in his personal life because he has placed himself in that "location" for such a long time? i would think it would be hard not to. you hear of writers who begin to think and act like their characters. and actors "become" their characters on camera. doing this over and over again, over the course of a long season…how could that not affect you in real life?

what do you think?
