    Let's be clear that this paper is not a factual document and has no valid sigma rating. The info in this video is not able to be proved and is scientific conjecture. Interesting none the less.

    You say memory of a pleasant food may cause cravings ? Must be all that fish I ate ( and still eat several times a week) growing up ,because fish ( any ) is my favourite food ,with salmon being my definite favorite fish . I probably don't eat red meats more than 2- 3 times a month . There are nights when I crave salmon like some hunger crazed starved seal( never mind the fact that the previous night I ate salmon ) and I have had weeks where I've eaten salmon like four times within a week. I CERTAINLY don't need to be concerned about lacking in Omega 3 fatty acids or high quality proteins . Hmmmm , 🤔 I wonder if I was a Seal or maybe a Killer Whale in a former life ,which is why I like fish so much.

    It sounds crazy but my daughter's mother's water broke during a full moon. When we got to the hospital one of the nurses screamed out "we have another one" and when we asked she said that a bunch of women had been going into labor and that it was a full moon. When we expressed our disbelief she said that every full moon they get busy with women going into labor

    I very seldom if ever crave junk food. If anything, I'm repulsed by junk food. I do crave nuts, especially high oil ones like walnuts and macadamia nuts , along with fruits and yes, even celery and carrots. I have very often been ravenous and when offered junk food, I refuse it . I'd much rather have a nice grilled wild salmon filet than a stupid Big Mac. I will opt for a fresh fruit salad without added sugar, or a couple pieces of fruit like oranges ,bananas or apples , or some mixed nuts when I am wanting a snack .

    Everyone talking about their allergy asthma like its no worse than allergies. Take a Montelukast and suck it up. Intrinsic asthma is the worst. Too much humidity? Too little humidity? Raining? Over 80 out? Walk too fast up a flight of stairs? Lifting weights? Walking too long? Overloaded at work? Forgot something? Can't sleep? Wake up too early? Stay up to late? Literally anything and everything else? Guess what? Have fun with an asthma attack only 4 puffs of rescue inhaler can fix followed by a nebulizer treatment to aid in the pain, stinging and excess tightness leftover.

    Aww boo. While I have both allergies snd asthma and they trigger each other, I don't think it's actually "allergic asthma". While they both suck, I very rarely get sick. 90% of the time I get sick from my allergies. I feel like my immune system is on over drive and fights everything off.

    I'm allergic to shell fish (shrimp ,crab but not lobster) and many pollens as it shows in so called hey fever and Sun rays (UV perhaps ? ) and whatever else I don't know and used to be able to write something on my arm and it'll pop up red just like a letter and itchy for a while. I started taking suedopheds everyday and after a few years I noticed I was highly aggressive and angry all the time till I realized that the meds were causing it so I switched to loratodine (claritin) after my doc's recommendations and have been on it daily for now 35 years or so. I can eat shell fish to a moderate amount and go in the sun without getting as much hives and generally less problems over all. I am wondering if I'd get adverse reaction from daily anti histamine (claritin) after all theses years on it though. I just couldn't be bothered with all the reactions I was getting to whatever is bringing these nasty symptoms at any given occasions so I decided to be on med everyday as in chronic desease treatment.

    So... umm... not to bring physics into bio class, but... the bacteria eats food that is made of the earth and on the earth... so if they consume one unit of earth, they aren't creating one unit of bacteria in addition to one unit of earth, but they are changing one unit of earth into one unit of bacteria... It's all organic matter that gets used, but basically it's neither creating nor destroying matter.

    O M G Holy Tamoly I just saw on TV a news story about Covid vax reactions. The Vax merchants have created a new excuse-diversion-distraction that is moderately creative......but so laughable. The Vax purveyors are warning that people shouldn't.....ready?.........wait for it......M I X vaccines by using different mftgrs. for the 2nd shot. This has anything to do with anything? Nope. People are recklessly switching mftgrs for their 2nd dose......for whatever reason? Nope. Nobody (or near nobody) is doing this mixing. The Vax makers created this from whole cloth to distract you should you see or know someone with a bad reaction to Covid vaccines. Man, these Covid vax makers are amazingly moral-less. And then they add this catch all-make you feel good- tag line. Remarkably, it's the same tag line the nuclear industry uses. Here goes...."Not to worry. The bad reaction to mixing Covid mftgrs will go away" which is identical to...." Not to worry. There was indeed a release of radiation at the nuclear plant, but the NRC ( a paid for and owned trade organization for the nuclear industry) says it is not harmful to anyone." I'm over 70 and every news item across lots of decades says the exact same thing about accidental nuclear releases. Hey, why spend on containment buildings? Nuclear releases harm nobody...ever. I digress, but similarly......Covid vax reactions harm nobody....ever. Same stepping aside from the responsibility of a bad product on both their parts. Big Money behaves so predictably that my German Shepherd can tell you what excuse they will use. BTWay..........no Covid vaccine reaction will be acknowledged AS a Covid vaccine reaction. Vax makers have been long skilled at denying that their product is responsible for any harm with their resolute and indifferent dismissal of responsibility for damaging kids with their vaccine products. The 1986 National Childhood Vaccine Injury Act....get this....holds Vax makers HARMLESS if they damage kids with their products. Similarly, Covid vax makers are not responsible for any Covid vax damage either. Hot stuff, these guys.

    I don't have any known allergies but one time I was eating trail mix and my face started swelling up. My airways were starting to close up by the time I got some benadryl a few minutes later. I'm not allergic to nuts - I still eat them all the time. All I could come up with was the fact that it was off-brand trail mix and it might have been some of the dye on the off-brand M&Ms. That was freaky and makes me think about people being caught off guard by stuff like this.
