What taboo subjects interest you?
1. Spontaneous human combustion.
My boss (and certain people) don't really believe in it, but it doesn't make sense to argue with documented evidence.
2. Sleepwalking murders. I think we all believe in sleepwalking in general, but people may not be quick to believe a murder can be the result.
Yet another case with documented evidence
(and a TV movie). If you can walk in your sleep,
you can obviously do anything in your sleep.
