As a youngster, Larry Bannister was one of about 28,000 Americans who contracted polio in 1951.
Like about 95% of children at the time who caught fell ill with the poliovirus, Bannister survived; the fatality rate for adults was about five times higher.
Bannister’s body still carries the effects of fighting the virus. He usually walks with crutches. If he goes shopping or knows he needs to be more mobile, he uses a wheelchair.
