Incorruptibles - What's your take?

For some reason this afternoon, I went on a search and have been reading off and on about the various religious figures that have been "incorrupt" ( meaning they still looking almost the same since the time of their death )

As this is ATS, and many have theories ( being spiritual and paranormal ) I would love to hear from ATS members in regards to these mysteries and what their theories are on why these bodies didn't decompose as others may have?

Who knows, maybe there really is somehting else out there, and these guys got it right. Maybe it's just coincedence. Maybe it's just lies.
Once again: who knows.
