I'm living in a developed country where I have never experienced starve, I may have experienced overweight more often. I know that, I understand that for a balanced diet, one cannot live with fruit and vegetables. Here I have two major questions about this. 1. If I haven't had ANY fruit or vegetables for a few months but I still take in meats and carbohydrates, could I have deficiency in vitamins of any kind? 2. If I practice fasting and do not eat anything at all for a week, and probably drink only distilled water, could I have deficiency in vitamins or other essential materials for life? I'm looking for medical or scientific advice rather than legend or u…

What is the little device? The Optometrist puts it on your eyes, and he/she can find out your naked eyes' vision directly? She told me my naked eyes' vision is about (L)10/20, (R) 10/20. which is very correct. The device is no bigger than a cigar case.

I have been allergically responding to the tap water, and I think I have worked out the hydrodynamics of it well enough to post it with some certainty. I don't know where my mom's apartment's water comes from. Any help understanding this would be appreciated. Main allergic response: The first thing I addressed was the tableware. Yes, tableware and silverware washed in tap water is the #1 culprit if no action at all is taken. My fingers were the number two culprit. Even accidental contact with fingers was noticeably aggravating to my allergy. Rinsing my fingers with store-bought water was ultimately more wasteful than simply using inside-out bags as gloves. …

In the South East regions of China, there have been a saying or legend for long time that excessive sex or masturbation will cause harm to one's kidney and vice versa, someone with an unhealthy kidney will have sex problems. For many years, there are also all kinds of supplements here sold legally which are advertised to improve men's kidney health or sex health and the terms kidney and sex are often put together and they are not selling badly. For long, I really hope to be clear, if there is any relationship between sex health and kidney's health, from the medicine point of view?

I'm reading this article, which arrives at the following conclusion: My questions are: #1 Is this a legitimate conclusion and #2 if it is, what is "extreme or exhaustive" physical activity which could achieve this overproduction of ROS above the body's antioxidant defense? What level of exercise are we talking about? I've just never heard of exercise potentially being detrimental to health, so I'm a little shocked. It goes against all advice you ever hear throughout your life where exercise is presented as an unqualified good.

I DO NOT mean when someone who possibly has mental illness and eat food taken from garbage bin. I mean, when you normally eat outside, you have little control over where they buy the food from and how the food is prepared, even if they are having an open kitchen that you can see through. The first thing is they will not usually wash the food so clean as you cook it for yourself, they are just working for money and focusing to have things finished quickly. Secondly, they may have touched their mobile phone full of dirt and bacteria and do not wash their hand afterwards. (It's very common). In some cases, not even rare, their body fluid may go into the food from cough …

A while back on another forum I posted: Please help find an earlier discussion on the Title topic as I'd rather post in that thread! Can't recall my exact words ... but something along the lines of: ==== Cold/flu lab study for students (as in a Univ. campus). You sign up to get enrolled into a study where researchers DELIBERATELY swab you (in nose) with a common cold / flu virus. You spend a few days in a lab where your symptoms -- if any -- are monitored. Something like this -- https://academic.oup.com/cid/article/40/9/1263/370417 You are paid to participate but -- unlike above -- students were DELIBERATELY infected. I reca…

I have come across many elderly, and I have never, ever heard one of them saying that they are free of all of the common chronic disease e.g. heart disease, diabetes, high blood pressure etc. Except that I once met one who looked so gorgeous, sporty, and healthy with good body shape at her age (e.g. probably around 65 and she was obviously very active in sports and exercises for a long time) and she said she didn't have any disease but I finally figured out that she was still diagnosed with high blood pressure, it was only because she didn't see it as a problem or she didn't even want to mention about it. I start to wonder if it's just almost going to be impossi…

For example, if skin or genital is rubbed with dirty public towel, could there be any sexually transmitted infection or other allergy problems? Chance is rare or just simply impossible at all?

I find that many toothpaste have expiry date, what is actually the chemical that will expire in a toothpaste?

Impotence is a known risk of taking 1mg Finasteride for curing male pattern hair loss but it's said chance is low. I asked doctor, he said it's possible, no comment on high or low risk. However, according to the health information provided officially here in my country they use the term "common" side effects for Finasteride. My understanding about "common" is that chance isn't low, at least. According to the instruction, it's about 2% if I do not remember incorrectly. In fact, how risky is 1mg Finasteride daily?

What does the evidence say (if there is any) on a) the safety and b) the efficacy of COVID vaccines in people with IgA deficiency? I assume both a and b may differ depending on whether it's an mRNA or old technology vaccine.

You'll often find charts like this that express the risk of various medical x-rays by relating it to levels of radiation from other sources. I'm wondering, is this a valid way of thinking about the risk? Because it makes a chest x-ray seem pretty trivial - exposes you to no more radiation than just 5 days of normal living (natural background radiation). Is it really valid to think of risks of chest x-rays in that way or are there additional factors here that would change the equation? Does the fact that a chest x-ray is 50 msc in one instant make it different and more dangerous than the 50 msc you are exposed to over five days of normal living from backgro…

There are possible up to hundreds of thousand drugs used in medicine, then there are just too many combinations between two drugs. Do they test each new drug with hundreds of thousands of other approved drugs before introducing the new drug to the market? How about three or more drugs? I mean it's not uncommon that a patient may be taking more than one drug because they may have a lot of diseases. How do they know if the new drug will not have problem when it is used together with possibly two or more drugs? For example, drug A + drug B + drug C or even with drug D or more. There are just countless combinations.

Some deny we have a soul, and that`s kinda okay, but I noticed that no one ever freeses in certain situations that are new, I mean, wouldn`t a brain have to be infinite advanced to never freese in a new situation that it hasn`t encountered before? Yes, like when you find yourself in a completly new situation, but still doesn`t just freese on you, especially when living in a society that`s always changing, this would be a problem you think, so I personally lean more towards that we really are souls that just take in the enviroment without processing it also, more just like take it in, a brain would have to be so complex in order to never freese, yes like almost infinite co…

I was listening to a conversation about potential cancer vaccines from The Spectator and at one point (43:30) Karol Sikora, who's the expert in the conversation, brings up this concern with mRNA vaccines of whether the RNA can insert itself into the genome of host cells and whether this might confer a cancer risk 30 years down the line. I'd never heard this possibility brought up during the height of the discussion about vaccines. Is this a legit concern?

Seems like there is strong evidence that ADHD stimulants save lives. https://www.additudemag.com/adhd-symptoms-coronavirus-risk/ "The COVID-19 infection rate is nearly 50% higher among individuals with unmedicated ADHD compared to individuals without ADHD" https://pubmed.ncbi.nlm.nih.gov/32629693/ "The white blood count rose by 1350 cells/μL (P < .033) due to neutrophilia, lymphocytosis and eosinophilia.

People find hyperactivity so endearing that they pay good money to see it in fiction. (Eg. Pinkie Pie, Jessie The Cowgirl, etc...) On top of that, it can also be a good way to burn the calories kids are generally known to want to consume in the first place. Society spends the first few years of a kid's life teaching them to walk and talk, and the next few teaching them to sit down and shut up. So why are we holding hyperactivity back? Why aren't we embracing it? The response I usually hear is that hyperactive kids can injure themselves or damage valuable property. So why isn't the response to give them protective clothing that would cushion their i…

We've had discussion about possible long-term effects of the vaccines. But now we're starting to see long-term effects of the disease https://www.nature.com/articles/s41591-021-01433-3?error=cookies_not_supported&code=15f3b4c5-db60-4dfa-b209-5334c13d613e Abstract: Long-term complications after coronavirus disease 2019 (COVID-19) are common in hospitalized patients, but the spectrum of symptoms in milder cases needs further investigation. We conducted a long-term follow-up in a prospective cohort study of 312 patients—247 home-isolated and 65 hospitalized—comprising 82% of total cases in Bergen during the first pandemic wave in Norway. At 6 months, 61% (…

It is known that sleep plays the most prominent role in decreasing “adenosine” and increasing “adenosine triphosphate”. But my question is: is there another way, therapeutic or non-curative, to reduce "adenosine" and increase "adenosine triphosphate"?
