Under: Opinion polls
19 Oct 2016


Now I know that this is not the most interesting subject but I had of dose of this in college statistics classes (3) for my undergrad and graduate degree. In business, statistics are mostly used for continuous process improvement or validating supply and product variances. But I would dare to say that the way most of us know about polling is during the political seasons. :(


In this article I will give an overview of opinion polls and the parts that might make a difference in determining accuracy. While I am no expert, I have been exposed and understand the concepts. I will have one really good link that will explain this very well and three videos that are nice visual aids.


One of my pet peeves with opinion polling is that the confidence interval is not published as the sample size and margin of error. Typically one can have anywhere from 90% to 99% confidence interval – a huge difference this can be as important or more important than the margin of error! And this information is not easily available. But the media perpetuates the myth that the margin of error is the only (or certainly implies it is the main) factor to look for in polling data.


Here are the parts of a sample:

  • Survey questions
    • not too complex
    • not bias
  • Methods to reach sample population
    • landline phone
    • mobile phone
    • in person
    • via internet
  • Random survey of sample population
    • you cannot select the people – that is not random (for instance all subscribers of a liberal newspaper)
    • does it include ethnic, religious, young, middle aged, old, and other variances in the population?
    • If it is not random or not representative of the population – it is not valid (sample error)
  • Margin of error
    • How likely your samples will answer how you predict in the range
    • a +/- 3% margin of error has a 6 point range that likely can overlap with some of the other candidates
  • Confidence interval
    • How confident your survey results range will be be as predicted
    • a 90% confidence interval says that 10% of the time – the results can fall outside of the margin of error


Here is an good article entitled, “Why polls can be wrong…” and below are the videos if you like your information delivered audio/visually.

You live in a city or country where you cannot carry a gun and your car breaks down. Your cell phone is out of juice but you see a store a couple of blocks down the street. Earlier in the day you had attended martial arts training and still have a trunk full of weapons. Now you see a bunch of guys approaching talking garbage.


I know this is a contrived situation but I had to figure out a way that one might legally have spears, staffs,  swords, daggers, clubs, tomahawks, and such to talk about the differences in fighting methods. Before we get going into this discussion I would like to mention my expertise is with unarmed combat (Kenpo Karate or Eastern Martial Arts (EMA) if you will). While I have always had an idea how to use improvised weapons (I understand Kenpo staff fighting methods) , I’ve only started practicing improvised weapons and historical European weapons (HEMA) in the last year or two.


I’ll will try to limit this discussion to the differences I see at each distance. To start lets take an unrealistic view of how an unarmed man might fight a long sword attack. :)

One of the fighter’s dilemmas is what happens when you grow old? I’ve written about this before but I want to take a slightly different tact other than entertaining the thought that old men will fight as good as young men. This is a case of diminishing returns. The older a man gets – the more his skill, strength, and stamina leaves him.


Specifically someone used to fighting any kind of sport karate (point sparring, continuous sparring, full contact or kick boxing, and even mma) will notice all of the hungry young pups giving the oldsters a run for their money. If an older fighter has not made the transition from fighter to coach at some point – what will be left? That is the point of this article. But first watch an old guy letting his gloves do the talking. I don’t know if there is any colorful language as these are not English speakers.

We hear a lot about how caring liberals are and how mean conservatives are regarding the Syrian refugee issue. This is probably fodder for tonight’s debate. For a long time this was difficult for me as a Christian because on the one hand, wanting to help people in dire straights (the reason we accept refugee’s) and the other hand, not wanting any more un-vetted refugee’s from war torn areas that we have no guarantee would give priority to victims of Genocide, Rape, and Slavery!


For me the question was answered when 56 of 10,801 Syrian refugees accepted by the US, were Christian. So considering the additional risk of ISIS seeding terrorists (no 2 year vetting) into the Muslim refugees – I would like to the US stop accepting any refugees from that war torn region. If the US is not going to favor arguably the most affected victims of the Syrian crisis (those being killed off for their Christian beliefs) then that is a deal breaker for me. I see no reason to risk American lives with any ISIS terrorists entering our country with Muslim refugees.


I’ll link to the genocide story here.


That is my opinion after careful consideration.


I totally understand if you don’t want to take my opinion – so I suggest you do your own homework. I welcome both pro and con opinions so long as they are civil, no cussing, no name calling… – just your opinion and any arguments. I welcome civil discourse and the only reasonable way good people can start to understand opposing points of view.

Under: karate, Sword Fighting

Wow that is quite a mouthful – Eastern MA compared to Historical European MA vs Olympic Fencing? Many might not understand the differences and to be truthful – it is hard to see the difference between Eastern vs Western martial arts. Is East Japan Kenpo, Okinawan Karate, Korean Tae Kwon Do, or Chinese Kung Fu? or we talking some Mongolian wrestling or Greko Roman wrestling? Are we speaking Turkish oil wrestling? All might be argued as the “East.”


How about HEMA (historical European martial arts) or Western martial arts maybe? If so what does that entail? So just the French and English Saber or does it include the Turkish Saber? So you see when we talk terms it is easy to be confused. I’ll state what I mean.


What I usually refer as martial arts to me used to mean Japan and China region martial arts. You see in America the word martial arts pretty much became that. Even though boxing and wrestling are “martial” and “art” in the sense that a fighter has to be creative to be good at fighting. The thing about martial arts is they have evolved to modern fighting methods that work better.


HEMA is easy to describe as it is using sword fighting as described in the old manuals by masters. Some use the word “military” swords but I tend to use the word “real” swords. People who train with HEMA try to fight they way sword masters of old did (you know when they last fought with swords). Today we don’t fight with swords so there is no real equivalent or next generation masters.


Or is there? One Olympic event is called foil, eppe or sabre fencing. This is a modern method with really light strips of metal (you cannot really call them swords). Arguably the foil & eppe were supposed to be trainers for the small sword but I don’t see the use of the sabre. The Olympian sabre is too light to be used the same way as real military saber. It is about the same as modern day point fighting. You cannot strike some areas and electric scoring is employed.


We also have the Olympics that have Tae Kwon Do (Korean karate like) karate in the games. Funny thing is the practitioners think it is fighting but to me it is playing. True if you get kicked with one of those kicks – it will do real damage, but if you are a trained fighter – there is not much chance of that – at least for me when I was younger. They score more point for kicks as they get more complex. Even though a knock out is a knock out is a knock out – not matter if a punch or kick or fancy jump spinning kick to the head. So it is a game.


So in both WMA and HMEA you have older methods but in WMA you also have newer methods. In HEMA not having modern methods is the point. I mean soldiers do not use swords in battle. As the styles of swords changed over the years – the sword method (except for the manuals) died out. Watch this video for an overview of the differences between historical and modern fencing and I’ll add my thoughts about karate and why I like HEMA.

Under: Safety

For those of you who don’t know – Target has been on the cutting edge of the lefty agendas by pushing the boundaries of safety under the guise of transvestites rights (or whatever they call themselves these days). You see Target earlier this year decided to let men self identify as a transgender (but I know them as transvestites) and use the woman’s bathroom.


Now I was used to Washington and NBC, CBS, and ABC trying to push “progressive” agendas and for the most part they have been successful. Roe vs. Wade happened so abortions are commonplace and recently the supreme court ruled allowing homosexual marriage in all 50 states.


So you would assume I would expect anything but this! What started as a backlash because North Carolina’s law mandating people to use the bathroom of their sex. In this article I will tell you as a self-defense (lifetime karate) instructor why men should not be allowed to use women’s rooms (I thought this was common knowledge).


First here is a video to consider ( #targetmissedthemark #boycotttarget ):

When I was a kid I used to watch how Kato (Bruce Lee in the Green Hornet) could beat thugs with knives and clubs in fights! Boy he made it look easy. I said at the time I wanted to learn how to do that. The thought that one could learn some secret techniques and then walk the back streets at night in confidence was amazing!


Well fast forward 50 years and I still think it is cool but I have more of a jaded eye. My older self realizes that there is a fair chance the guy with a weapon will win. Is it possible to fight a short dagger without any weapons? Sure but is it smart? No. Unless you are trying to collect on a life insurance policy, I would advise you to hedge your bets a bit.


First take a look at this HEMA (Historical European Martial Arts) club owner for his take and then we will discuss. If you don’t want to watch the video – the take away is you should fight back with a weapon – improvised or not.
