Correlation is not causal inference . Yes they know sugar causes diabetes, Robert Lustig and his team at California found a causual inference on sugar ,heart disease and diabetes. But there is no casual inference on dietary fat. The real truth is eat real food that came from a tree, plant or animal. Otherwise don't eat. Do bread come from animal, plant or tree ? No so don't eat

7.5 miles down and that's it. So many stories, he says it was too hot to drill more. Russians say it was so hard they kept ruining the drill and nothing was working. They want you to believe there's a hot molten core and their evidence is volcanos. Or that we have this magnetic core yet if you heat a magnet to almost liquid state it loses all magnetic properties. It's one story after another without being able to prove anything. Believe what you can see and can be demonstrated, proven, and duplicated. Everything else is just splaining away how there was no need for intelligent creation. Yeah, a big explosion sorted everything out for us. Like a tornado going through the junkyard and leaving a 747 behind. Use your brain and not someone else's imagination.

Tell the truth, stop with the monkey meat BS!!! AIDS did not come from a monkey, Ebola is a biological weapon created by the US Military as well!!!

i used to take mdma every week for 2 months. almost 1 gram per week. without the anti-oxidents i would be dead right now. i took multi-vitamins, 4000 vitamin C, 400 E, ALA, ALCA and for serotonin and dopamine production - 5htp. with this combination i got no harm from the MDMA toxic, lots of energy day after and i could take it without loosing the effects because the body wasn't in trauma after each use since i insert so much anti-oxidents and multi-vitamin. B3 specific and 5htp is the combination to make sure your body take the 5Htp and use it for serotonin and dopamine and not for creation of B3 since it's first in priority.

There's no such thing as negative and positive charges. That's conceptual and childish. There are no imaginary electron bb's being transferred. The so-called ‘electrons’ are not particles, not objects or subjects, but are the dynamic principle of discharge, and are certainly not charge carriers. Fields are not particles, nor “electrons”. There's only charge and discharge. Friction is the resistance to motion which takes place when one body is moved upon another. This increases inertia. Electrical tension/charge (pressure) builds up at the atomic level. Depending on the intensity of the charge/pressure in that object, it will discharge once another object comes into contact with it. There are no polarities. Opposites don't attract. It's force and energy dissipation, pressure mediation.

Could send clean soft water (has cloride via sodium chloride already in it) from the Atlantic to every home, then run soft / salt water to showers and toilets, then people have a small distiller at the kitchen which disinfects and removes salt for drinking, about a gallon a day per adult. If the shower water is too soft people can buy a water de-softener, or whole house reverse osmosis system

I have this happen all the time, but the bigger quirk for me is knowing I will receive a message or notification a second often less, before it happens. I've gotten to the point that I can grab the phone before it goes off.

A lot of theory, a very materialistic (Hellenistic) view that denies ghosts and spirits. How long has man been recording climate data? The extrapolation of a few decades or hundred years of data during and up cycle (that may become a down cycle) does not prove much. Cooling the planet may cause the next ice age to be much worse. The fact is that profiteers have been reckless (destructive in the pursuit of money) and governments with their military bombs and missiles have also had a significant effect. Stop all armies, navies and air forces. By the way, oil does not come from decomposed fossils and CO2 increases plant life. What madness, do the "educated" people know anything of value and why do governments believe the lies?

Ive had sleep hallucinations for as long as I can remember, typically 3-5 times a week. However I never hallucinate as Im about to fall a sleep, its always if I wake up in the middle of the night. The hallucinations never resemble anything Ive done or seen while awake the previous day. It can range from a figured shape in my room to one or several persons or animals moving around me, that are very clearly visible. Some of the more severe hallucinations include my surroundings completely transforming into something else. In these cases I can clearly see my furniture disappearing and I can feel and touch things that arent there. For example my room turning into an elevator thats trapped and I can walk around and feel the buttons on the panel. Almost jumped out of a window first time I experienced this full on hallucination. If its simply people walking around my bedroom sometimes Ill have my doubt whether my roommates have come into my room. But when I see monster-like figures or giant spiders Ill usually just ignore it because I know its clearly not real. Ive become quite chill with it over the years. Ive been lucid dreaming my entire life also, and Ive read there may be some correlation between waking from a lucid dream and having hallucinations.

Count the teeth: if they have an irregular number of teeth or if the teeth are weird shapes, it's probably fake.

I worked for a company at the corporate level and we found it dangerous at meetings to not appear to embrace every stupid move or concept presented by the Higher Ups. At one meeting a few of my colleagues and I risked it to see how deeply we could kiss-up to the presenter, and the biggest and stupidest grins and smiles and nods appeared to really please the bozo at the podium.

I'm convinced that this is true. I've seen photos of very slender people irl look bloated on particular photos. I'm on the leaner side and I can look at photos of me when I was 18 and certain body parts (upper arms) look bulkier than the rest of me. It's usually crazy stuff on selfies now like bloated looking fingers or a wider nose. I believe cameras were meant to do this... On the flip side of things, there are people who look stunning in their pics, but not so great irl.

In dogs and wolves, bare teeth is in the list of "calm signals". They inspire the others to calm down. It is via threat, but eventually it could evolve to directly inspire calm without the threat.
