Paralympics

The 2012 Paralympics are about to begin: Paralympics are for people with disabilities such as limbs missing or blindness.
 Yesterday was the  opening ceremony for the Paralympics.
  You should try and watch these brave, determined athletes if you can.
                    The Paralympics are not as popular as the Olympics. The sports in the Paralympics include archery, athletics, boccia, cycling, equestrian,
Football 5-aside, Football 7-aside, Goalball, judo, power-lifting, rowing, sailing, shooting, swimming, table tennis, sitting volleyball, wheelchair basketball, wheelchair fencing,
wheelchair rugby and wheelchair tennis.
I wonder how this man competed in the Olympics not the Paralympics ?
