Joining the air force @ 26?

Lets see first a little history about myself. Unlike some of the q&a I read regarding joining the military @ an older age I have no college education what so ever, tried to go to college but they turned me down for every grant and i wasnt willing to get a student loan. I dicked around in high school so the grades on my transcript arent all that good either. Im 26 yrs old, a high school grad (by the skin of my teeth) class of 2004, been working a crap job @ my local walmart for four years and my life is going no where. I guess my question is do you guys think I can join the air force???
