Actual Fighting
This section covers a lot.
1)Martial arts.
TKD,and other martial arts. it is good to learn martial arts to
protect yourself. The idea here is to learn moves and techniques to
take your opponent before the opponent takes you down. Always be
flexable in your attack by not restricting yourself to moves you
have learnt.
2)Fitness.
it is good to have some exercise program so that you have the
stamina...with the strength to take down the opponent.
Now i will cover the scenarios.
scenario 1, Cornered into a corner.
This may happen without you realising it. It may be your friend or
a group of people.
If 1 VS 1
if you have the courage to take him/her down, then go for it. Hit
hard,if you want, go all out. but beware of counter-attacking if
the opponent learned martial arts.
If 1 VS many
In this case, it would be wise to watch the suitation and act
accordingly. if you cant handle them, RUN!
run to somewhere public, or somewhere you are sure they can lose
you.
(i am not sure about this, but there is a chance that if you are
attacked in public,there will be some others joining in to
help/harm you.)
Wide in the open
This may be a case of scenario 3...which you may have to get up
quickly and fight back. (i have never been in this kind of
suitation yet, so i cant share my experience.)
Kill or not to kill?
This is a widely debated topic. especially in singapore.
If the Threat level is so high that it endangers you and others,
you may go in for the kill. Fitness and tactics matter a lot this
time.
There are no rules if you are fighting for your life. Keep that in
mind and go all out according to your ability.
