...we could turn on and off our senses...

...then one would be to choose not to hear something particular, or not taste something if it's disgusting. Or if someone farts in a lift (elevator for you who may not know) then, just turn off your sense of smell and it won't bother you. Same goes for touch. Just hurt your leg? Turn the sense of touch off and you are fixed. Luckily we have some control over our eyes, what with being able to close and open them at will. That level of control would probably be enough. Most importantly of all, I would be able to ignore you more easily! Finally, as a fun fact for you all, please note that humans have between nine and 21 senses as opposed to the five you all know and love.
