you can lose your sight or hearing and they are senses

couple of words could exchange places but good content

thats why they are called red herrings

Red Herrings are where you could have it in another group, but not swap for something in that group. If it still works the other way round there is not one unique answer so it is a poor grid. If you can lose it and its a sense you can swap them

Read and digest what iffy says

Sorry folks about the words that could swap places. I rushed and didn't think it through although it seems a good way to promote discussion !
