I notice every spelling mistake people make too, but if you think about it- the fact that we still know what people are talking about is one of the things that makes us superior to computers
As far as ghosts & science.... I would love to see more research into it, but unfortunately it's not very practical. Ghosts are no threat to our National Security, nor would more knowledge about them benefit us very much.. so therefore the research funds are not exactly flowing strong in that direction.
