I'm not entirely sure what you mean by 'whipping' a punch. So I'll just go with what I know. There are 5 basic punches and the rest are just variations on them. Jab, Cross, Hook, uppercut, and overhand. Each of these punches is not just a different arm movement, but a different series of body movements. If we compare a jab and a weak side hook for example.

Jab: starts in the toes, and rear thigh, tensing those to give a rock solid base. Let the flex radiate upward to your core as you exhale sharply involving your abs and diaphram. Rotate your wrist as quickly as you can to unfold your arm straight out. You want your fist to impact at the exact moment that you fully clench your fist, the exhale completes and you flex your rear knee. Keep your center of balance directly under your shoulders the entire time, do not shift into putting more than 30% of your weight on your front leg. Your aim point should be about three inches behind the contact point. As soon as you make contact counter rotate your wrist to bring your arm back to your guard. This punch should be as fast and crisp as possible. You typically aren't looking for a knockout with a jab, you just want to take a small opening and wedge it open for a bigger punch.

Hook: From your back leg shift your weight from sode to side to your front leg. Load your front leg and prepare to drive back to the side that your weight just came from. This punch is all ass and obliques. Exhale sharply as you tilt your elbow to aim. Come across with your fist as hard and sharply as you can. Fully clench your fist and finish your exhale as you make contact. You want to drive this punch through something, I like to aim for putting the punch into the inside opposite wall of my opponents skull if I aim for the head and I want to drive it to the spine if I aim for the body. At the point of impact your entire body should be a wall of flexed muscle. Recover by twisting your elbow back into place for your guard.

In either punch you want to make an imaginary box, the top is your eyes, the bottom is your floating ribs, and the sides are the tips of your clavicle. This box extends out from your chest. Your hands do not leave this box. They are stuck in the box. We aren't getting fancy here, your hands stay in the box. And breathe dammit.

Not all CNS depressants are born equal.

Something like morphine (or any μ-agonist), which strongly depresses the breathing reflex, has a much more narrow therapeutic index than for example, alcohol. Benzodiazepines don't depress respiratory function on their own, but when mixed with alcohol or opiates they have a synergistic effect that can be lethal.

Edit: More than one reply pointed out that this was less than layperson accessible, I hope the following helps somewhat.

μ-agonist: A type of receptor found in the brain and the GI tract among other places. Agonist just means something that binds to those receptors and makes them work. Opioids are a well known example of these substances.

Therapeutic Index: How much of a drug it takes to have the desired effect, compared to how much of the drug causes toxicity. Some medications have a very broad therapeutic index, many antibiotic types are the classic example of this.

Depressed Respiratory Function: In this case it's all about the signals your brain sends to keep you breathing. Opioids are famous for depressing that part of your brain, sometimes with lethal consequences. Benzodiazepines are not really known for this, although technically they do have some effect.

You've noticed that the share price drops by the dividend amount on the ex dividend date. Naturally, because a share that's going to guarantee you $5 if you own it tomorrow is less valuable than one where you have to wait for a year to get the $5.

What you don't see is the gentle pressure pushing the share price up as the year goes by, and next year's dividend date gets closer and closer. A share that guarantees you $5 in a six month's time is worth more than a share that guarantees you $5 in a year's time. When the ex dividend date is only 3 months away it's worth even more.

You won't notice that and can't notice that effect for ordinary shares, because there are so many other factors that affect the share price much more strongly. But you will see this exact effect if you look at the price of exchange-traded fixed income instruments: these are tradable on the exchange but give you literally a fixed amount of cash regularly. The price drops on the ex date, then slowly climbs until the next ex date. You earn the same amount per day no matter how many ex dates you cross.

They never said that viruses are alive, so I have no idea why you even mention it. And it doesn't matter anyway, unless you can show me an objective universal definition of that word which at least a majority of relevant researchers can agree on.

Being alive and having a "reason" is not the same. A complex but definitely not alive machine like a car has a purpose and does it's functions for a reason. Ultimately, all things do what they do for a "reason", be it just the laws of physics.

If instead you meant "reason" in its second meaning, based on consciousness, then it fails just as well. Bacteria are considered alive by almost everyone, yet they have no mind to speak of. They don't reason with themselves at all, they just do like a bio-machine.

If you think that it matters if viruses or prions are "alive", then you are wrong. It simply does not matter, what counts is what they do (with or without "reason"), and that is exactly what the post your responded to described. No researcher would suddenly change their approach for treating or preventing rabies or covid if you or anyone else decides they are (not) alive.

See this??

I'd say that's ... three white birds high, and three white birds wide. You agree? There's like, nine complete white birds you can see. Right?

Now I tell you, that's a snapshot of a much bigger mural, painted on the side of a building.

Can you find out where that 3x3 birds section IS on that huge mural?

You probably can't, because no matter which section you focus in on in the mural, all you see are 3x3 birds.

Make sense so far?

The patterns made by the hats ... they don't repeat like that.

Take a look at JUST the darkest blue ones.. They don't really repeat like the white birds do.

And the math people who figured this out, realized that no matter how big the mural is, the dark blue hats in one section, do not resemble the same pattern of dark blue hats in any other section.

That should blow your mind.

A worldwide law?

FYI there are lots of places in the world that do not have this specific law. Or it doesn't get enforced.

They all have national companies that still use the unsubscribe function. There is a Mimecast guide on keeping your e-mail reputation with ISPs up so you don't get spamlisted. Basically conforming to RFC 2822 SMTP, which includes unsubscribing functionality.

One word, fiber. Fruits have fiber which prevents excessive sugars from getting absorbed in our body.

Refined sugar is devoid of fiber and gives you the entire dose spiking blood glucose levels.

BTW fruits means fruits. Not fruit juices. Fruits juices fall in same category as refined sugar as it doesn't have fiber.

What I’ve noticed playing football in my teen years is the kids that say they should be the quarterback, usually aren’t the best pick for that position, but they want it. Then they aren’t very bright either but they want to be a doctor or stock fund manager. They have a personality where they want the most glamorous positions.

If a company is making a steady profit, but otherwise everything is remaining the same then one of two things should happen:

  1. The company keeps its profits in the company, meaning that the company gets more valuable over time since as well as the profitable business it now has cash in the bank
  2. The share price increases slightly each year and then falls when it pays the dividend, repeating a constant cycle each year

The shareholders see the same return either way, either in cash or an increased stock price

They are, they started 10-15 years ago based on the results of work 20 years ago. You get the chip today. 9-14 years ago they got the results from the manufacturing 19 years ago and couldn't incorporate the changes into the the plans already in motion the previous year, though sometimes they can and you get internode improvements either in yeild or performance.

South Park has never really been my cup of tea, but I think the big reason is, it’s funny and it’s clearly satirical. They’ve also built up a lot of goodwill with different factions because they’ve ‘offended’ everyone over the years, so in a weird way it’s seen as operating in good faith.

I also think it’s worth noting that most comedians or comedy acts that have gotten ‘cancelled’ have happened when they’ve veered too far away from “funny jokes” and towards “mean spirited attacks”.
