The conclusion will be that by effecting me Berryz have changed the destiny of the world.
The argument is Chaos Theory or if you prefer the Butterfly Effect, http://en.wikipedia.org/wiki/Butterfly_effect :
The phrase refers to the idea that a butterfly's wings might create tiny changes in the atmosphere that ultimately cause a tornado to appear (or prevent a tornado from appearing).
An example I can glean from my own life is: I reject girls (on a psychic level) left, right and centre because with Berryz my standards have become so high and so DIFFERENT that most women I encounter don't fit the bill. This means romances that didn't happen, marriage that never occured and birth(s) that never will occur.
I hope this doesn't constitute too negative aproach to fandom but as always I am my own person and have my own way :|
