How do I know about breathing....?

So how did I find out how useful breathing is ? By almost losing it in a fire accident some years ago !
At the time I was a professional singer - mainly opera.. I opened the door of my room, which I hadn't realised until then was an inferno !
Flames engulfed me and searing heat scorched down my windpipe like a flame thrower, extracting the oxygen literally - in a flash..!
The blast of the fire threw me down a staircase, luckily by the 'phone - I just had time to dial 999 and give the house address before my voice ceased to function. My hair was wrapped in a damp towel, having just been washed,I was wearing specs' so my eyes were not burnt - the skin on my hands "melted" and I passed out.....
Regaining semi - consciousness in hospital some weeks later, I remember hearing a most eerie sound , quite scary - the kind associated with what technicians create for dinosaur "language", and lots of gasping noisy "sucking in" of air ....!
When fully conscious later, I realised it had been my lungs and throat trying desperately to survive. There followed quite a battle of will and brilliant nursing which effected my survival.... . so, here I am, some thirty odd years later and still going strong - a miraculous re-birth ..... and knowing enough about respiration to be able to help many who have breathing and phonatory problems.
My lungs have minimal capacity, but I can still sing, which is why I know how little air one needs to activate those tiny vocal folds which are so delicate ......
The restoration of my voice was a surprise - it wasn't expected to work at all, ever again, by specialists !......So here we had another miracle. it's all so simple if you just know how !! keep watching and find out more, and pleeeease - keep breathing ....
