National Guard ?

Well I have been thinking of joining the Army National Guard. I am kind of torn though as I have already been in the military full time and I do not want to do that again, but the benefits such as medical insurance and retirement are nothing to shake a stick at. The wife is not thrilled with the chance that I could get deployed, and I cant blame her for that as I am none to thrilled with that possibility either, but I feel like I need to do something to change the direction my life is currently heading.
