From my point of view, it doesn't matter whether they know how
to climb a tree, or survive outdoors, that is important. These are
all SKILLS. Skills can be learnt. The more important thing is their
ATTITUDE. If they have a bad attitude, then no matter what you
teach them, they won't learn anyway. Like one poster said, you can
learn to climb a tree in a few hours; you can learn to survive in
the jungle in a few days. But if you have the wrong attitude, all
this knowledge wouldn't be worth nuts, cuz the first instance you
lose your aircon and your pc, you will give up alr.
For eg, look at this clip

Near the end, compare the attitude of the 18 year old soldier
about to go to Afghanistan with the average attitude of the 18 year
old Singaporean boy.
