I was just wondering how old everyone was when they joined the military? I am pretty sure that I am going to join the marines but I am 22 going on 23. Have any of you joined at this age or do you think it is to old. Another thing....I wear contacts right now. Do i have to were that butt ugly glasses while I am in Boot Camp and after that??? If so I bet the are a lot of pissed off people with those glasses on!
