Paul Alexander was just six years old when he was struck down by polio, which left him paralysed from the neck down.
Unable to breathe by himself, Paul was placed inside an iron lung, which he has relied on since 1952.
Paul has spent a lifetime in and out of the iron lung, and developed his own way for breathing that he calls ‘frog breathing’, which allowed him to spend some of his life outside of the metal contraption.
The ventilator, which resembles a terrifying metal coffin, requires patients to lie down inside, with the device fastened tightly around their neck.
