teapoo,
You may wish to consider some negative aspects of joining the ADF. Over 12 years, consider erosion to your social skills and lack of individuality development (herd mentality). Many find it hard adapting to civilian life again. You will most likely be spending extensive periods devoid of diversity, the opposite sex, and with many of not the smartest people in the world. Only need to look at their TV advertisements, not very believable, and obviously not pitching to anybody even slightly intelligent. Not only question would you feel at ease living with these people, but would you feel comfortable killing other people?
