Both of Ibkens posts describe how I am - I become spatially disorientated easily when visual cues are taaken away or disrupted - despite many years of training in a tai chi exercise sometimes called 'sticky fingers' , a kind of shadow combat done with a partner with closed eyes, that is designed to hone the senses. Well they don't feel that well honed these days, and I do not like being in the daek. at all!
