A falling bullet has a much lower speed than one that was just shot.

What makes you think that? The Its potential energy at the top of its upward trajectory is not that much different to what it was when it came out of the gun - and it will be pretty much the same when it gets back down to the same level it was fired from (thanks to gravity, with a small effect of wind resistance).

People are frequently killed by bullets being fired into the air - as described in this article.

Unless you are willing to consider a revival of eugenics, we are headed down a dark path.

Be like Hitler, you mean? That didn't exactly end well, did it?

Maybe we just need to consider sharing the work around more fairly. The current trend is opposite to that - with more and more workers doing unreasonably long hours. It's time for governments to legislate a maximum working week of 30 hours.

[......] few would consider the top third to be "rich".

Few of the top third, you mean. Rich people rarely seem to consider themselves rich - they often complain about how hard they've got it and they always seem to want more. But by any sane standard the top third are extremely rich - whether you compare them to the bottom third or to the top third 50 years ago.

They certainly have far far more than their fair share of the worlds resources.

I'm somewhat stunned that you don't think the medical community would notice that.

I don't know why you're stunned. The medical industry's not very smart. There's a lot of things that seem like they should be obvious to anyone with half a brain, but which don't get picked up by the medical industry for decades. They're also almost entirely driven by what makes profits for the pharmaceutical industry. Over prescription of antibiotics anyone?

Another example is biopsy. It's been glaringly obvious to me for decades that the worst thing you could do to a suspected cancer is to chop into it - but chopping into it (biopsy) is the first thing quacks normally do when they suspect a lump could be carcinogenic. And, guess what, research has finally found that biopsy (along with other standard procedures) can lead to metastasis (Juratli et al 2014). And it's usually the metastasis that kills people. It doesn't bear thinking about how many people have been killed by the so-called "treatment".

In a couple of decades, maybe someone will think of doing some research into the role of fluid retention in obesity - unless they already have, but you didn't bother citing it.

Sorry, no. Obesity is not caused by bacteria (or genetics, or "conditions"). Obesity is caused by consuming more energy than you actually use.

Citation? And what part does fluid retention play in this? None, according to your theory. I think you're wrong.

Honestly, how a site full of self-professed science geeks keeps ignoring basic thermodynamics continues to blow my mind...

If you're so smart, explain the thermodynamics of fluid retention.

Of course, if you were really as smart as you think you are, you wouldn't post a/c.

As someone who is married to someone who has struggled with her weight for all her life, and has done everything including a strict 1000 calorie diet with very little results, I KNOW there is more to it than "just don't eat as much".

Have you considered the possibility that at least some of the excess weight is fluid rather than fat? The body seems to retain fluid in response to conact with environmental contaminants. In my case (and i'm not really fat), i get fluid retention from breathing in the fumes pumped out by computer cooling fans - presumably mainly flame retardants. It has other effects than just fluid retention (cough, headache, etc) and different computers have different effects - presumably because they use different classes of flame retardants - but the fluid retention is quite noticeable and can happen quickly.

All electronic equipment seems to be drowned in flame retardants before it leaves the factory, as does furniture, carpets, etc. Flame retardants are volatile organic compounds which may also be persistent pollutants, and have been linked to an array of different health impacts. Some have been banned (e.g., polybrominated diphenyl ethers (PBDEs) and dibrominated phenyl ethers (DBEs) - banned by the EU in about 2005) but they just keep replacing them with other ones, which have unknown effects. Brominated flame retardants seem to be being phased out because of health concerns, and replaced with fluorinated ones- which i supect may prove to be worse.I believe brominated flame retardants were developed to replace chlorinated ones - again because of health concerns.

Anyway, i think fluid retention caused by environmental toxins merits investigation to determine its role (if any) in obesity.

Maybe, by and by, we'll find that some obesity is caused by the wrong gut bacteria, and some by bad habits.

Maybe, but i doubt it's as simple as that. I think the dogma that obesity = excess fat is severely confounding our understanding of this issue. One thing i never see discussed anywhere is the contribution to obesity made by fluid retention - which i suspect is considerable.

Everyone seems to assume that excess flesh is fat, but that's not necessarily the case. The body can retain fluid in response to environmental contaminants of various types and most people live in ever more toxic environments. If you seal people into houses with electronic equipment, furnishings, carpets, etc, all of which have been drowned in flame retardants - volatile organic compounds which have been linked to many different health impacts - it seems likely that at least some of them will end up with some degree of fluid retention as a result.

Antibiotics flame retardants, and shit food are probably the three main contributors to obesity. Wrong gut bacteria is one product of antibiotics use.

There is not one single reason why a mobile payment system is necessary, needed, or an improvement over cards.

Yes there is - so a new bunch of parasites can skim off some of your money.

The cost of the new system won't come out of the profits of the retailers - it'll come out of your pocket. Or phone account or whatever.

It's always puzzled me why so many Christians fear death, when they claim to know they are going to a place vastly superior to this one.

That's because they can only delude themselves to a certain extent. Deep down they know that when they die that's it. Nothing. But they try and believe that's not true. So, of course, because they spend their whole lives desperately clutching a delusion, they never come to terms with oblivion. All but the most gullible ones live their lives desperately fearing reality.

An optimist believes we live in the best world possible; a pessimist fears this is true.
