I think obsessions evolve from one to another. As child I was into collecting comic albums, poststamps (or was that a hobby?)
then Indians from North America became the big thing in so much I became a specialist in Indians now of South America ( I lieved with them for a while and wrote a book, which I just finished and I am still looking for a publisher), music and dance was an obsession and I exelled in it (am a good dancer in so much that people ask if I have been to a dancing school), contrary to the asexuals I have been obsessed with sex since I was 12.
