3 WRONG Things People THINK in STREET FIGHTS

Off-Duty Chicago Officer Robbed https://bit.ly/2CHLudt The video starts as just another day in southside Chicago. Three people start confronting and trying to attack one guy. I'm assuming they were making a lot of noise about it because she comes out and confronts them as a mediator of sorts. Three of the guys walk off a few seconds later while she speaks with the fourth person. Then out of nowhere, once she turns her back and starts to walk off, this goofball ATTACKS her! All the reports I read said he was trying to take her gun, and it did seem like that's what he was trying to do until the armed woman WHO told him exactly what she was about to do. To which he responded, trying to call her bluff, she would have to do it. Then, as the saying goes, he messed around and found out. Now let's talk about all the lessons to be learned here in which I talk about in the video: One: The gun is the equalizer. Two: Keep a round in the chamber. Three: Gun control doesn't work on criminals. Four: The Reality of open carry Five: Get some type of concealed carry insurance I say that because even though this woman was not charged with anything, the man's family sued her in civil court for 10 million dollars. Unfortunately, we live in a society where you can use a gun to save your life, but the family of the person you saved yourself from can turn around and try to sue you into bankruptcy. So you may beat the criminal case, but you'll still have to deal with the civil. That's why it's essential to have some type of concealed carry insurance like you get when you become a member of USCCA because you'll not only have access to attorneys to help you with your criminal and civil case, but they'll also cover you for any collateral property damage that may occur during your self-defense shooting Let's say she missed a couple of those shots and hit a car or a window; with a USCCA membership, you could have all of that covered. I think USCCA is the best, which is why I work with them, and they do offer my followers special FREE bonuses to become a member with a 365-day money-back guarantee.

Entrapment Footwork for Easy Knockouts – It's sneaky and it works

These are the molecular machines inside your body that make cell division possible. Animation by Drew Berry at the Walter and Eliza Hall Institute of Medical Research. http://wehi.tv Special thanks to Patreon supporters: Joshua Abenir, Tony Fadell, Donal Botkin, Jeff Straathof, Zach Mueller, Ron Neal, Nathan Hansen Support Veritasium on Patreon: http://ve42.co/patreon Every day in an adult human roughly 50-70 billion of your cells die. They may be damaged, stressed, or just plain old - this is normal, in fact it’s called programmed cell death. To make up for that loss, right now, inside your body, billions of cells are dividing, creating new cells. And cell division, also called mitosis, requires an army of tiny molecular machines.DNA is a good place to start - the double helix molecule that we always talk about. This is a scientifically accurate depiction of DNA. If you unwind the two strands you can see that each has a sugar phosphate backbone connected to the sequence of nucleic acid base pairs, known by the letters A,T,G, and C. Now the strands run in opposite directions, which is important when you go to copy DNA. Copying DNA is one of the first steps in cell division. Here the two strands of DNA are being unwound and separated by the tiny blue molecular machine called helicase. It literally spins as fast as a jet engine! The strand of DNA on the right has its complimentary strand assembled continuously but the other strand is more complicated because it runs in the opposite direction. So it must be looped out with its compliment strand assembled in reverse, section by section. At the end of this process you have two identical DNA molecules, each one a few centimeters long but just a couple nanometers wide. To prevent the DNA from becoming a tangled mess, it is wrapped around proteins called a histones, forming a nucleosome. These nucleosomes are bundled together into a fiber known as chromatin, which is further looped and coiled to form a chromosome, one of the largest molecular structures in your body. You can actually see chromosomes under a microscope in dividing cells - only then do they take on their characteristic shape. The process of dividing the cell takes around an hour in mammals. This footage is from a time lapse. You can see how the chromosomes line up on the equator of the cell. When everything is right they are pulled apart into the two new daughter cells, each one containing an identical copy of DNA. As simple as it looks, this process is incredibly complicated and requires even more fascinating molecular machines to accomplish it. Let’s look at a single chromosome. One chromosome consists of two sausage-shaped chromatids - containing the identical copies of DNA made earlier. Each chromatid is attached to microtubule fibers, which guide and help align them in the correct position. The microtubules are connected to the chromatid at the kinetochore, here colored red. The kinetochore consists of hundreds of proteins working together to achieve multiple objectives - it’s one of the most sophisticated molecular mechanisms inside your body. The kinetochore is central to the successful separation of the chromatids. It creates a dynamic connection between the chromosome and the microtubules. For a reason no one’s yet been able to figure out, the microtubules are constantly being built at one end and deconstructed at the other. While the chromosome is still getting ready, the kinetochore sends out a chemical stop signal to the rest of the cell, shown here by the red molecules, basically saying this chromosome is not yet ready to divide The kinetochore also mechanically senses tension. When the tension is just right and the position and attachment are correct all the proteins get ready, shown here by turning green. At this point the stop signal broadcasting system is not switched off. Instead it is literally carried away from the kinetochore down the microtubules by a dynein motor. This is really what it looks like. It has long ‘legs’ so it can avoid obstacles and step over the kinesins, molecular motors walking the other direction. Studio filming by Raquel Nuno

Bruce Lee - founder of Jeet Kune Do - a pioneer in modern Mixed Martial Arts (MMA). I got tired of watching this video, on other YouTube channels, with the audio & video out of sync; so I audio-corrected it. I also tried a rudimentary upscale, with very little success... but, all in all, I think it's better overall. Much of what Bruce discusses here is expounded upon in his book, "Tao of Jeet Kune Do", which I highly recommend.
