The NS is a compulsory conscription that every able bodied male Sinkie has to go through. It does not specifically apply to me only. The only way to avoid is to renounce your citizenship. It's a small sacrifice of my 2 and a half years, but I had also picked up numerous skills during that period and made the full use of the stint.
I made it beneficial to me, especially when I was fortunate to be posted to a unit which suits me perfectly. I was even given a commendable/appreciation plaque by my unit when I ROD. My OC even invited me to his house for Christmas parties and my RSM even allowed me to drive his car home whenever he was on field camp duty. How many NSFs can be accorded these privileges by their regular superiors?
