Tracy is a Dr of Osteopathy and is particularly interested in the creation of ill health through physical, emotional, chemical and traumatic means, affecting the nervous, skeletal and endocrine systems.
She is a sponge for data and has looked at firm data on clean water, good food, dry homes and sewerage systems which are amongst the secrets to good health.
She speaks of a fascinating study on rabbits with meningococcal bacteria and this brings up the vaccine debate.
Being in the political arena where she feels the implementation of policy strongly influences people's lives, Tracy talks of the use of poisons in the name of conservation, and the use of agri-chemicals.
How can we look after the health and well-being of the people?  This is her driving question.
