A man has survived 70 years inside an iron lung machine against all odds.
Doctors doubted six-year-old Paul Alexander would live much longer saying he "shouldn't be alive" as he lay flat inside his iron lung - but 70 years later he's still going.
Paul was left paralysed after being struck down by poliomyelitis, a serious viral infection that can affect the spinal cord, in 1952. That year, an epidemic had swept through Paul's hometown of Dallas, Texas, US.
