Too old for USAF & Flight School?

I'm 22, recently decided to buckle down with college and will have my AA in a month or so. I've wanted to be a pilot since I was 6 and learned that my grandfather was a mechanic and worked on p-51 mustangs. However like most dreams we have as children that seems to be a ridiculous idea as you grow older. This one has kind of always stuck with me in some way and I'm starting to think about it a lot recently. I understand that only a VERY select few become fighter pilots, while other end up flying cargo or fuel. I've heard everything there is to hear about the difficulty and slim chances of becoming a pilot. I didn't come hear to hear more about that. I would love to fly for the USAF or Navy, however hard it is to land on a carrier lol. My only question is, am I too old to go down that road? I've heard about some "high-school to flight-school" program which may have been my best bet, but my head was elsewhere when I was in high-school. Any and all answers are appreciated, thank you.
