Suppose that someone develops liking (or even obsessing with) something since very early life, e.g watching football from age 5 to age 25. Is it possible to consciously make oneself hate it when one is older?
Can the converse happen also? Is it possible to hate something at a young age and then consciously make oneself like it when older?
If this "brain rewiring" can happen, what are the methods to achieve it? Is there any research on this subject?
