im thinking either navy, coast guard or air force. i have smoked cigs for the past 3 yrs and realize i need to get myself in much better shape before going to boot camp. im not unathletic by any means. im just worried about how i will fare in boot camp. ive never lived away from home. i think of myself as a strong person though and think that if i put myself in that situation i will be able to get through it with flying colors. also, which of the 3 do you think is the easiest boot? which one provides the best path for someone who is looking to join to get out of his hometown, experience an adventure and finish college?
