Im thinking of enlisting...seriously. I know im old, Im blind in one eye... (so I dont know seriously where they would put me) but I wanna be in shape! And I lack dicipline. Thoughts? Id like to be in the navy, just cuz airforce scares me... heights... bad. And I know I cant fly cuz Im out one eye..... Im not sure the "gun" stance on military since Im blind.... Im wondering.
