it was reported that in havana the change in room actually made a difference but when going into say perhaps bedroom where they spend hours sleeping the feeling of sickness was concentrated.i don't think the russians or anyone else are wasting time on developing a weapon that makes people feel odd for a few minutes, but if they were, you think listening to music on your ear buds would stop it?....¿
i use noise cancelling feature and don't have to hear anything i don't wish to..wear mask to say anything and shade my eyes..it's my version of deprivation tank on the cheap.
