I am 31 and in good shape. I have been seriously thinking about it.
Wife isn't to pleased. We were just married this year. I often thought about joining the service but opted for college and the parties instead - Have sometimes look back and regretted that decision.
My BA I could have got at anytime, joining the Service at 18/19 would have been something else!
This is just too funny. As I'm reading this thread my wife comes in and sits down across from me (she can't see my screen) and she says, "So you ran 3 miles this morning, walked 5 miles at lunch and rode your bike 10 miles this evening? Are you going back into the Army?" ;-)
Talked to the National Guard about going in as an Arabic linguist. I'm prior service so I can go in over age 35.
Still need to lose a few pounds before I can make a commitment, however.
POA2 - you can go in up to age 35. Go talk to a recruiter. Since you have your BA see about going to OCS.
