Today I learned the history of tea and that it's consumption around the world is only second to water. I also learned that the tea trade was once responsible for the spread of opium addiction in China when instead of silver, English merchants began to offered opium in trade for tea.

Ha!

I had a look and have to say that the jury's still out on this one. Correlation isn't causation and the sample is small. This needs more research.

Today I learned about the history of cannabis. It's native to central Asia, dioecious, and only its females produce THC.

As I understand, negative mass should involve a repulse/attraction effect, where positive (+) mass is repulsed by negative (-) mass while (-) mass maintains an attraction to (+) mass. The overall effect causes acceleration as (+) mass is continually repulsed and chased by negative mass. However, the physicists discovery discussed in that SFN link describes a fluid that accelerates backward when the nature of a negative mass elements, as I understand, should accelerate forward towards repulsed (+) masses. I believe the video link I posted discusses that discovery's acceleration conundrum. Nevertheless, I understand the substance and its effects much better now.

Though I'm not quite sure it describes principles relative to negative mass, your video link certainly does provide an easy to understand example of "behaves unexpectedly." If it is indeed relative to the idea of negative mass, I now have a firmer understanding of that idea. Thank you.

Today I learned about negative mass and, by learned, I mean I have absolutely no understanding of the physics nor comprehension of what it is. The science is light-years beyond my understanding.

Today I learned that nearly two-thirds of all cancers are caused by natural mutations amid our body's cellular replication process. Our body replaces trillions of cell throughout our lifetime. Essentially, the shear number of cell replacements predisposes the process to errors that can produce cancerous mutant cells regardless of our lifestyle or exposure to carcinogens. It seems, in a majority of cases, getting cancer might just be bad luck rather than an unhealthful lifestyle.

Today I learned why some motorcyclists crash. It seems that most crashes are due to poor cycling skills and inattentiveness.

I wondered about that as well. The article did says the longest was an oil well but didn't say what that meant. The article also referenced a SciShow video link which it did not provide. Perhaps the details are in that nonexistent video link.

Today I learned what's at the bottom of the world deepest borehole. It's in Murmansk, Russia and it's 12,262 meters (7.5 miles approx.).

Yes, you're quite correct. It was 2.5 instead of 1.5 years. 1.5 years was their initial calculation, whereas, 2.5 years was their final more precise calculation.

Today I learned that the Laws of Relativity and it's relevant math suggests that Earth's core is 2.5 years younger than its surface and, according to this SciShow Space video, the center of our sun is 39,000 years younger than its surface!

What an interesting fellow!

You know what? I like a little vinegar too, particularly on my fish-n-chips...yum...it's true, we Americans are getting fatter.

I don't use it often but yes, certain ketchup brands here are a little more sweet than tart.

Now, I do. Fascinating!

They are a decadent pleasure for which I bear no shame or remorse. Try one...just one... Ha!

Perhaps it was an exaggeration...but I do have a weakness for a certain sweet confection (Swedish Fish) that I, sparing no expense, buy in bulk and simply must have daily and often. In your garden you say? Hmmm...what a likely lovely place for them to live.

Yeah, sugar intake doesn't increase hyperactivity but it can and does enhance mental acuity, which could translate into a more alert and active child. 150 to 250 years ago, sugar was a more precious commodity. Here in the states, the wealthy kept their sugar stocks under lock and key. As to our average yearly sugar intake, I think mine is more like 300 lbs....I think a lot, so I require a bit more than average.

Ever wonder, How Your Brain Powers Your Thoughts? Well, today's your lucky day. That link is to a DNews Seeker video, which describes the process and how a protein (Glut4) in our neurons extract glucose from our bloodstream as we engage thought. Enjoy!

I think an annual physical fitness requirement is essential for active military service members. Alas, that sort of physical regimen for me, a civilian, is far in my very distant past. Nowadays, ,the measure of my fitness is managing a leisurely stroll in the park with frequent park bench respites. .

Perhaps your right, but this one might have missed a few steps...or maybe he's just missing a little something upstairs. Apologies.

Indeed, I'm surprised he broached the subject of time dilation again after it was closed. It just a maniacal carousel.

I simply refuse to go down that rabbit hole with JohnLesser again! Either he's trolling or willfully ignorant.
