haha... as opposed to what? liberty without purpose??? 
life is the same at work as well... will kena arrow, will kena sai
kang, must know when to take cover...
when doing things, must be organised, must be responsible, must
think before doing something stoopid, must bear in mind
consequences...
so isn't it good that u learn these valuable social skills while in
NS rather than facing them the first time when u start
work???
believe me... u can see very clearly whether someone has done NS
before or whether someone was exempted...
