One of my bigests regrats was when I belived in the brazilian's arm system. Last year i had to did my enlistment in the arm, but how I was in the second year in the college, have myopia, i'm the only child, thought it would be easy to be dispensed, but i was wrong.
First because, a lot of oficers (sargents, capitans) were wearing glasses, so myopia wasnt a excuse to didnt serve. Then when i told to the sargent that "sargent i cant serve because im in the secont year of my course in the college" he answered me "WHAT ARE YOU SAYING? YOU ARE SAYING THAT THE SOLDIERS ARE STUPIDS? YOU THINK I DONT STUDY?", therefore college wasnt a excuse to didnt serve.
In that moment i started to enter in panic, because if i had to ingress in the arm i would have to stop my college for 1 year. Then i start to think in all kind of excuse to didnt serve...i thought in say that i used drugs, but if they asked for exame, i would be in troubles. I thought in say that i was gay, but if they like it, i would be in a huge trouble.
But finally in the end of the history, i was dispensed because, my mom live only with me, and "she have some problemas of health and depends on me to help her", but i had my hair shaved, and lost all my july's vacation there.
So if you have to enlistment your self in the arm, dont belive in the system like me, get a fake medical certificate, to not be in danger.
