Fighting with handicaps

Let's face it.

When people say fight, it's not uncommon to picture two guys, in the pink of health having a go at each other.

What would you say to a fight where one party is a knife-weilding assailant, and the other is a singlet, shorts and sandals wearing backpacker with a pack the size of a baby elephant?

By handicap, I'm referring to a physical constraint that can compromise one's safety and ability to survive in a fight/ assault/ physical confrontation or whatever you want to name it.

Chums with physical ailments like busted knees, crippled arms and such. Lads wearing spectacles.

Or people with temporary non-physical handicaps like that backpacker, or a mate carring the wife's grocery items. Even tight jeans can be a handicap.

And what about women? With all the stuff they lug about, and their clothing, the shoes, even.

You get the picture.

Ever given a thought as to how these people might defend themselves in different scenarios?

I wish I had enough cash to buy myself a personal video camera. Maybe I could give some ideas that could help. It's hard to put them in words, mates.

Ive tonked someone with contacts in, he started blubbering they had cut his eye... shouldnt of pushed me over that wall then should he?

when i was walking on a crutch for my bad knee i didnt feel as vulnerable as the last time I damaged my right wrist... could mean my whole sense of confidence comes from my hands?

in an ideal world: I think once a student has done some basic training they should work drills that force them to be handicapped by environment (stuck in a car, shoved into a corner, over a wall) and by what they are wearing, carrying or even tying a limb down to represent injured limb... I say in an Ideal world, I mean in my training dungeon for brainwashing american prisoners into killing machines that the US govmt is setting up right now...
it wont be a top priority thing, it will be in the last stages of training to teach my army of hypnotised assassins to improvise around circumstances to apply their skills.
