Mind bums carry serious retardation that can be contagious and have ability to drag you down with them if you don't take precautions. The most effective ones are: ignoring the mind bum completely and .. well that's about it, any exposure to a mind bum can be deadly to you intellect.

Man, I feel so exhausted after this 2 hour meeting with these mind bums, I feel like my IQ has dropped 5 points at least.

Dave's dead, he committed suicide after these mind bums kept bombarding him with A4 page long e-mails asking the same question for half a year. I guess he never learned to ignore them.
