Just to clarify:-
I have no medical or first aid qualifications. That is why I posted the link without comment so that others could read and digest.
It certainly was not my intention to be confrontational or mischievious and had no desire to cause individuals to be grumpy. I really didn't expect this particular post to be contentious.
I confess that after Dajen's first post I felt a little concerned, I worried that the advice offered was incorrect.
In Dajens later reply he posted a link to the NHS's very worthy campaign which, to my untrained eye, appeared to confirm that the advice offered was correct.
Campaigns on social media do follow the principles of chain letter campaigns. They are very successful in getting a message out very quickly to millions, worldwide. I see nothing wrong with that particularly when carrying an important health message.
But as Littlesprite commented the fact that this topic has been debated has helped to strengthen the message so I thank all for your contributions.
