Puppets.

That there are no depths that Hunt will not sink to in his ongoing dispute with the junior doctors is not something that should surprise anyone. That some of the high ups in our own profession should ally themselves to Hunt should also come as no surprise. So we shouldn't take too much notice of the statements by the Academy of Royal Colleges or the blatant threats of those bullying shits at the GMC too seriously. The name of the game here is to maximise the chance of a gong for various people, by seeing who can get his tongue furthest up Hunt's arse. My money is on Dickson, He's had the most practice.

The BMA has finally stirred itself, they should only contemplate one way forward.

Crows

A few days ago DZ was driving along a motorway in a rural area. The road was quiet and up ahead I noticed a small group of crows engaged in a motorway banquet, feasting on some unfortunate creature that had probably had too close an encounter with some vehicle. Just then I was overtaken by a motorcycle going at some speed.



 As he sped along the road the crows began to scatter and take off, but one was a bit slower than the rest and the biker struck him knocking him to the side of the road in a flurry of feathers. The biker wasn't in any way affected, but the crow was certainly killed instantly.
Google search will confirm the widely held notion of the "sentry crow". One crow that acts as a look out for the others preoccupied as they are with eating. He calls a warning of approaching danger.



 So why did he not warn his mates in time?  Perhaps he was just not used to vehicles doing that sort of speed. I mentioned this to a biker friend who confirmed that crows often fall victim to bikers, and he explained to me the reason.

Apparently the sentry crow, like all crows is perfectly able to say "car", but unfortunately none of them can say "motorbike"

Cupping??!!

An article in the Guardian today draws attention to the practice seen in some US athletes at the olympics of "cupping"



 The article quite rightly points out that the practice has no scientific basis, nor any evidence of efficacy, and that any benefit perceived by the athletes is likely to be pure placebo.

However, it is just possible, maybe, that there may, theoretically, be some real physiological effect.

"Oxygen flux" is the amount of oxygen delivered to the peripheral tissues per minute. Assuming no pathological physical impairment of blood flow it is very much dependent on haemoglobin value. The higher the Hb, the more oxygen the blood can carry, and the greater the oxygen flux. Up to a point.......  But increasing Hb also increases blood viscosity and thus reduces flow. There comes a point when increasing the Hb causes such an increase in viscosity that the resultant reduction in flow completely negates the effect of increased oxygen capacity, and further increase becomes counter productive. This is well known to happen in polycythaemia. So there is an optimal value of Hb at which O2 flux is maximal. The exact value comes as a surprise to many doctors. Optimal Hb for maximal O2 flux is (in old units as befits DZ) just 10g/100ml, significantly lower than the normal 14 or so.

If the bruising caused by cupping were to significantly lower the Hb level in the blood, it would improve peripheral blood flow, and possibly, improve performance. You might get a similar effect by bleeding, or applying leeches.

As this study shows, removing 500ml blood certainly doesn't seem to have a negative effect. And as far as I'm aware, unlike performance enhancing drugs, it's not forbidden.

Quiet

Perhaps I should have noticed, but, tucked away in my statistics pages is the information that, at some time in the last two weeks, total page views on this blog went past one million.

 In fact, despite my not having written anything for some weeks I'm still getting quite a lot of views, though why I should currently be getting so much interest from Russia at the moment is a bit of a mystery.

It makes me feel I really should make more of an effort to put up the odd post. So why have I been so quiet? Busy with other things, certainly, but not that busy. maybe I've run out of things to say, or don't feel so strongly any more about things. Or maybe I've been plunged into the pit of despair by the failure of our new Prime Minister to banish Jeremy Hunt to some far flung backwater.

 I'm still here. Maybe I'll think of something.

Spin off

In all the political turmoil and blood letting, am I alone in fervently hoping that one of the casualties will be our detested Health Secretary?

Celebrity stupid

There is an inexplicable tendancy among human beings to look for information, not from the qualified and knowledgeable, but from the rich and famous. A prime example would be the reporting in the newspapers today of the view of the footballer David Beckham on theEU referendum. So why is he considered an authority? Not only has he spent much of the last 20 years living outside the UK, he's not actually renowned for his intelligence. These quotes will perhaps illustrate my point.

I definitely want Brooklyn to be christened, but I don't know into what religion yet.

My parents have been there for me, ever since I was about seven.

Alex Ferguson is the best manager I’ve ever had at this level. Well, he’s the only manager I’ve actually had at this level. But he’s the best manager I’ve ever had.



So in this vein this is Dave Asprey. A very wealthy American businessman, who, for some reason, has so far escaped an entry on the“Encyclopedia of American loons”. He has a fairly standard list of looney views, including advocating homeopathy and inventing his own, unremarkable diet. He's nonetheless considered very influential with the public in the field of health & fitness.

Possibly my favourite bit of delusional bollocks coming from him is his assertion that men should not orgasm more frequently than dictated by a special formula, Age, minus 7, divided by four. Using this formula your average 16 year old would have to wait about 2 days between events. I think most young men that age would be hard put to leave it two hours. 


And DZ at his age, should be leaving it over two weeks! Fuck off Dave, you're having a larf! Apart from anything else we have prostate cancer to ward off.

Dave has also firmly announced his intention to live to be 180 years old. Good luck with that one Dave. I think you'll find eventually that, as all Discworld fans know, when death comes to visit you he's not come for an argument.
