There are more arguments which go against the identification of 'I' with body. If someone loses some body part for some reason, that person retains the identity of 'I' there is no loss of identity 'I'.

Human body is complicated. Every cell is supposed to a living cell. Then there are groups of cells, organs and so on. But identity of 'I' is one and the same for all. What exactly is 'I'? Is it heart? Is it brain? Is it head?

If it is claimed that the whole collection neatly packed in the skin is body, then the question is what happens after death? The collection is still intact.

If it is claimed that living body is 'I', then there is trap. What keeps body living? Because the word 'Living' is what designated as 'I'. Dead body is not 'I'. It can only mean that the body has not capacity of its own to keep itself alive and therefore the living entity is different from the body.

Consider the dreams. The physical body is resting on bed and 'I' keeps on moving places in the dreams. Is 'I' the physical body? But physical body is stationary while 'I' is not. Thus the physical body cannot be 'I'.
