Do you know what is facts or myths?

Most of the behaviour modifications are considered myths unless scientific evidence is provided. For some behaviour modifications there is insufficient evidence from good clinical studies, but some recommendations are supported by expert and patient experiences. All behavioural changes are grouped below into 3 categories.
