Joining the U.S. Air Force?

[Adam A]

I plan to join the U.S. Air Force, as soon as possible. I have a couple of questions.

As far as basic training, what kind of shape should I be in? Any tips or anything as far as surviving both mentally and physically? So far I can run about 3 miles, and I am taking the physical preparation seriously, but I don't want to overlook anything.

Secondly, to all those who are in the USAF or other branches currently, what is a job that you wish you had done? I am sure this will vary based on personal interests, but If there are some awesome jobs out there (great bases, "easy" schedule or duties, exciting, etc) I want to make sure that they are on my list.

So far I am thinking about Air Traffic Control, Contracting, Public Affairs, Crypto/Airborne Linguist, and Optometry.

I know the AF has way more applicants than open jobs right now, so I want to get kind of a long list of acceptable jobs going before I go to MEPS.

Thanks for any and all input.

Peace
