As was said: To the believer no proof is required, to the sceptic, no proof is sufficient
Well, I cannot simply declare ghosts for non-existent (see valid Captain's point). But I quite believe it to be so.
The TV argument: the point is not in the strength of the magnetic fields. Resonance is what counts. No wonder, our neural system is circuits and stuff, even if it is organic. It had to come one day.
What really unsettles me (but does not surprise that much), is the fact that a human brain can be influenced with the help of special magnetic fields. More exactly, that emotions can be influenced or even created this way. And the first research uncovered ways to feelings like... 'the sensed presence', fear, and other experiences. Now, imagine targeting such a weapon (yes, a weapon!) at a large mob of people, whether they seek God or nice football match. Not all would be influenced, but...
It's getting ugly from this moment.
