Another 'Study' shows that joggers/cyclists etc need a much bigger 'Distancing'...although it is meant to advise those tormented souls not to 'slipstream' but to echelon...avoiding the leader's emissions. 
IMHO...heavy breathing and sweat will give out more potentially contagious moisture...and deep breathing will suck more in. Exercise is SO Healthy for All !!!   
At least, being a 'toxic' smoker, MY breath/smoke-plume is visible and so can be evaded with ease ! 

I always knew exercise was bad for you

I agree, the so called "fit" blokes at work have more time off sick than any one else, colds, Coughs, headaches to say nothing of sports injuries that cause them to go sick.

I went our for a run today and forgot something.  I'm old, fat and can't run!

As far as I'm concerned, two out of three ain't bad.

What were 'they' reckoning ?.....We should be doing 10,000 steps, a day ?

I must be WAY short of that.

(Do I get any bonuses for climbing over '5 bar' gates, 'cos I'm too lazy to go and get the padlock's key ?)

Only if you don't fall off....


Sumat on Beeb2? couple of months ago reckoned that 1/2 hr intense walking is superior to 10000 steps..

The "10000 steps a day" thing has no basis in science as a target, invented in 1960's Japan. BBC link.

Although obviously walking for 10K steps is probably much better for you than only walking (e.g.) 3000.

A wake up call in today's Telegraph 15 hours ago  from Roziz Sebur that the South Korean Health Authority (KCDC) have reported that of  91 Covid patients in the city of Daegu who have "recovered" , some 51 have tested positive again.

This undermines what medical opinion presumed  about the virus, in that once a patient recovers from a "normal" virus, the human body has evolved the capacity to generate the appropriate antibodies to nullify new attacks.

Has it already mutated to a new strain that compromises the human body's immune system?   Already the range of virus infection has been demonstrated in that Hancock was up and about in days, whilst Boris went to intensive care, and thousands died.

What of the 40 who are unscathed ?  Do they have the antibodies ? What degree of infection did they suffer in the first outbreak?  What does this mean to the concept of herd immunity ? Are we about see a second surge as China eases up on lockdown?

There was also a public information advert some years back featuring former Scotland rugby player, Gavin Hastings, in which a brisk 20 minute walk was advocated.

That doesn't sound good.

BUT....I'm assuming (trust me, I'm not a Doctor)....That even if you have had the virus...there would be nothing to stop you picking it up again....And being dangerous, in the respect of being able to pass the wretched thing on again.

Who knows, though......Simplest form of 'life'* can 'evolve' far quicker than everything else, as it has 'generations' that only take minutes/hours (?) to come into being.

*I'm still not sure whether a virus is supposedly classed as 'life'....Or just a self replicating strand of RNA.

Is it possible the issue lies in the validity of the testing? If the tests aren't entirely accurate it could result in misreporting.

Or they caught a secondary illness but still have the genetic markers from coronovirus in their system.

Or even a weakened immune response could potentially arise from the body struggling to beat it first time round that it's not had enough time to recover the immune system to produce the required antibodies again in high enough volume?

There's still a lot of unknowns in that regard, and the tests aren't 100% accurate.

I'm not even sure if the tests would indicate a mutated strain, as it would potentially present different markers...

Its a breaking story, but due to its implications, it will run.

Not my area of expertise, but I understand there are two tests :
1. the test to identify infection is a simple swab to the tonsils - or even nasal snot.   The point of facial entry (with the eyes) to the host.
2. The antibody test - which usually indicates the presence of abundant Covid 19 antibodies, is a pin prick blood test.

The KCDC is well respected and transparent.  Their management of the current outbreak is textbook in terms of testing and containment.   But then they had the experience of MERS in 2015. 

There has been some concern about the pinprick test, I think the Guardian had a story about it the other day that I'll look for when I get a chance.


The other test varies quite a bit - when I had a covid test recently (in Toronto), it was both nostrils and a rectal sample. The rectal sample was the least offensive, given that they ram the test sticks right up your nasal passages (pretty much up to the brain, it seemed).

Let's be fair: There's a whole tonne of things "with no basis in science, invented in 1960s Japan", and are now swallowed hook-line and sinker by captains of industry (or maybe just industry) as panaceas to all their ills.


I think this is the part of the dream where the Austrian doctor says: "Lie down on the couch - tell me bout your former employer".

Let me pile in:

You're quite correct, Viruses (Viri?) are not considered alive, they're a very nasty biohazarrd that invades and hijacks your body by messing with the normal cell production process.

As for the Covid-19, it already had 2 of the "Big three" charcteristics of a truly lethal pandemic.
1. Asymptomatic transmission - You can pass it on before you know you have it.
2. Viral Co-infection - Most virual illnesses are exclusive, having one means you cannot catch another, exceptions HIV, Hepatitis and Covid-19 are nasty (Very nasty).

The third one, which had not been observed in Covid-19 until now:

3. No long-term immunity - Many viral illnesses are one-off things (Measles, chickenpox), but some can infect a person again (Influenza).


If the suspicions of the Korean scientists are borne out (I doubt they have sufficient evidence of primary and secondary infections to be 100% positive at this point).
This blows a hole in the side of any herd immunity (or any other type of acquired immunity) strategy for gradually mitigating the virus.


Hate to be so gloomy.
Happy Easter all.

Steve, what are the implications of this for vaccine?

Pandora's Box springs to mind!
