Don't worry, you can work in the chow line. How good are you at making SOS.I'm 41 now so I am rather outside the prefered range of draftable people.
Add in my bad back, allergies above average IQ and generally unbreakable disposition and I am all but useless to the military. If I don't see something as being to my advantage I'm not trainable in it and being forced into military service at my age is definitely not something I would see as being to my advantage in life. .
