Physiology & Medicine / Re: Why do people get hungry after alcohol?
« on: Today at 07:31:07 »
Quote from: paul cotter on Yesterday at 18:28:53
It' a long long time since I did any biochemistry but as far I remember alcohol drops one's blood glucose levels and hence the hunger. Mary Jane has a different mode of action, thc activates the cb1 receptors in the brain and these trigger hunger. A pharmaceutical company had the smart idea of using a cb1 antagonist to assist weight loss, as it would have the opposite effect to your "Mary Jane". The product, rimonobant, worked fine at it's primary job but had to be withdrawn as a side effect of suicidal depression reared it's ugly head. Not surprising really. 
Not cool man.

Alcohol itself carries many calories, this you would think would compensate for food as well as glucose loss, it also dehydrates meaning there is less water in the body.

Everyone now has a legal right to reproduce, and everyone else has a duty to keep the offspring alive 'cos of its Yuman Rights, so on average the species will be getting less fit and more selfcongratulatory..
More than that, over the millenniums, rulers have begot many many children, the rich have carried forward wealth, these genes are the ones that are prevalent, as was seen in the haemophilia of Queen Victoria's families.

Survival of the fittest?

Your personal definition of ' fittest ' to me is Unknown.

As per Darwin, i personally think, We have cracked open n split apart his definitions.
(reproduction)


Thou important to note, the essence of his Theory remains fragrantly intact.

" The 1 most adaptable to Change, is the 1 that Survives. "
C.D.
Well, for example heart problems. I personally know of 2 families who have heart problems in the male lineage, going back generations none made it to 50 up until recently, brothers uncles etc. As is seen in footballers, heart problems are usually exposed under duress, or fitness testing.

But what's that got to do with astronauts messing around splashing water all over the place inside the space station?
Oh. I think that the connections must be protected from water, the condensation would be problematic if not, pooling and subsurface water must be a problem.

People of yesteryear knew how to build. Just take a look at the railway stations, cathedrals of engineering, although cathedrals themselves are cathedrals of civil engineering. Those vaulted arches and spires are not due to god.

Given that we have had thousands of years of society, with it's "don't kill" ethos and "no adultery/bigamy" dictate, has this bred into the human population inherent illnesses?

As I suggested, imagine even if the desert had melted in hundreds of places, that what not be evidence of the Exodus.

There were finds maybe in Jordan like a civilization suddenly changing pottery craft methods, diet from pork to sheep, and a mountain in Sinai with mineral water marks and a natural raised area from which Moses could speak.

It was hard to keep the Bible, it has been under threat, For Christians and Jews, the Pentateuch is more accurate than an Egyptian hieroglyph rock face carving.
So, I guess the answer to the OP remains no, there is no evidence of the exodus.  Agreed?
What standard of evidence will you accept? Is there any evidence that Joe Biden is the us president ? Or is is all fictitious make believe and lies.?

In many mythologies and religions there is a golden age/garden of Eden and then the illnesses come (Pandora opens her box).

Now all of these things have one thing in common, they are the beginnings of society, bringing social norms, outlining prescribed non bestial ways of behaving. Darwin on the other hand says survival of the fittest and let the beasts run riot.

Has the advent of society led us to destroy ourselves?

Antibiotics. Proper strong stuff from hospitals. I have heard of doctors end up prescribing those dainty little bottles from the supermarket that are the gut bacteria stuff.
If you think that (UK) supermarkets sell antibiotics you are not well enough informed to be giving advice.

Antibiotics are noted for upsetting teh stomach- bloating is a fairly typical symptom.
PC is suggesting treating bloating with drugs likely to induce it.

It's as if he didn't understand this bit.
Quote from: scientizscht on 01/06/2023 11:51:55
Please note: this is not seeking medical advice, just scientific evidence/opinion

Ahh thank goodness for the disclaimer.

The question asks for something to kill bacteria in the gut, the hospital grade antibiotics will do the job, hospital ergo not without very serious doctor prescribing. Killing the bacteria ergo no bacteria ergo needing something to replace the bacteria ergo little hospital pots of microbiotics or gut bacteria.

Ergo I wonder what happens if you drop antibiotics into bacteria culture is it like coke and mentos.?

....before the NHS was established.
Before the NHS, did most working-class and poor Brits rarely, if ever, visit a doctor?
Yes, before the NHS people had to pay for doctors so the working classes had very little access to non emergency medical attention. There where free hospitals if you where maimed awfully.

It is left to the reader to pick out the useful bits.

The best definition of industry I ever heard was "organising men, materials, machines and money to make stuff that people want." Note the last four words.
Do you notice that Edison tried and failed thousands of times before successfully produced technically and economically viable light bulbs? He might have thought even many more experiments which he did not continue to carry out because he expected they would fail.
We are prone to survival bias that we often forget that those who don't survive had once existed.
That was a croat

Funny, that. I thought lots of workers were striking for higher wages. So it's just an unwillingness to turn up and do a job. Clearly, then, Brexit has turned the country into a paradise where you don't need to work at all. 
Yes, it's an unwillingness to turn up and do a job, the conditions are contested by the unions and by people who look for retirement, have medical retirements, change jobs regularly. Many people who where near retirement age after corona didnt want to come back.
