VIETNAM. VO Van Trac with his mother MAI Thi Nghiem. Trac, born in 1969, exhibits symptoms similar to Minamata disease. He spends 24 hours a day on a wooden bed behind the house. His legs are twisted and only half-developed. He writhes and grimaces ceaselessly. The muscles in his arms and body are in constant tension. His fingers have been bent back so far by spasms that they appear double-jointed. He is unable to talk. 1998
