In turn, I was moved to do this because I felt people had over-reacted to his post, interpreting it as being dismissive of genuine and serious cases of asthma which (as he himself later explained) it was not - and neither is mine meant to be.
I have other anecdotal evidence such as: a former friend of mine (we just lost touch over the years) who freely admited that he was registered as asthmatic but couldn't remember ever having an attack. He loved getting the inhalers on the NHS though as he used to have a quick squirt before inhaling certain, smoking related herbs to get a 'better hit'.* His brother is also asthmatic and again does not remember having an attack but thinks he might have been registered asthmatic 'in case' he had the same problem as his elder brother.
Again, I am not diminishing what can be an extremely serious condition and I have nothing but sympathy for those who suffer from it, but I do have some sympathy for tnt666's assertion following my own experiences. Of course, these experiences form a very small sample and I am in no way claiming that such over-diagnosis is widespread as I do not have compelling evidence of that.
*Not being an indulger I have no idea if this was effective or merely psychosomatic.
