About 20 children in shorts and vests gather at a swimming pool on a sweltering afternoon in Nigeria's economic hub of Lagos. A coach holds the hand of a boy who is blind as he demonstrates swimming motions and guides him through the pool while others take note.
It was one of the sessions with students of the Pacelli School for the Blind and Partially Sighted, where Emeka Chuks Nnadi, the swimming coach, uses his Swim in 1 Day, or SID, nonprofit to teach swimming to disabled children.
