"Okay Nigel, please enlighten us by revealing how many EXACTLY of the 1000's of dowsers out there have shown this 'lack of ability'"
Normally an exact number would be hard to come up with, but not in this case as I know of exactly none who have shown that ability to others (based on my personal observation and Googling. Under controlled conditions, that is.) I'm prepared to bet my caravan against your house that that's the EXACT number you know too!
Being committed and getting off your arse every weekend doesn't make throwing knucklebones an effective form of futurology or dowsing a real phenomenon.
"Beats sitting in your armchair or looking at a computer screen and googling away to gain your information from like many do!"
If that's a dig at me so be it but you should know I've been interested in dowsing for many, many years since before Bill Gates had a pot to piss in and I do know a bit about it! As does George. Why demonise us (which is what's coming across loud and clear)? Don't you think we'd RATHER it was proved to be a real phenomenon? You'd have to be bonkers not to wish it was.
