What about us middle-aged guys??

[no more mr. nice guy]

Hi Guys!
My very first post here. I know the PUA/Seduction community is largely a group of younger guys from 18 to 35 + but what about us middle-aged guys? You know, if your in a LTR be it you've been dating this one girl for a long time or married(with or w/o kids), if you don't have your game down pat and so it seems we're always improving and refining that, what happens when your forced back out into the jungle of the dating scene? Sorry if that seemed like a loaded question. Its inevitable that once you reach your middle age and beyond you'll be forced back into dating again if you become divorced or going thru a break up.
Maybe my question should more specifically be...can a middle aged guy apply PU as well and reach the same level of success as younger guys?
