Theresa John is 28 years old and a slow learner. Most of her life has been spent in special schools or training centres. Like her friends Debbie and Susan she has had to put up with the insults and patronising attitudes of so-called normal people. 'I just don't like the words mentally handicapped - it's not fair calling us that' (Debbie aged 25). But for Theresa life is changing, she has become a star athlete and is the favourite for a gold medal at this year's Mini Olympics.
