Steve-
I took the physical last August. I really wouldn't worry too much about it, although, I know that's easier to say than do (and I worried before it, too). I had mine at Newport with about twenty other guys. If I remember correctly, the physical started at about 7, or so (I could be wrong - but I know it wasn't at 4:30 or anything like that). We first filled-out paperwork and then gave blood samples. After that everybody went to different stations for the rest of the day. For example, some people went to the dentist (different building) for what, basically, amounted to a check-up. Others, at that time, had their eyes checked. This was probably the most intensive part of the physical. You'll have your eyes dilated and it's REALLY uncomfortable, especially if you've never had it done before (I hadn't). Other stations included a checkup by the flight surgeon, an EKG/ECG, and height/weight/anthro. measurements. All in all, you'll spend a lot of time sitting-around waiting for the stations to open-up, and it took a total of about four-five hours. I guess it could be different, though, if there are less people taking the physical at the same time. Anyway, good luck, and, again, don't worry about it. If there's anything you should worry about, it's the PFT!!!! Let me know if you have any other questions.
