You forget that when Jesus says His words are "Spirit" and "Life" that means they are not to be taken seriously.
Why this language means that is never explained, but it is axiomatic.

Sounds to me like you better start paying attention to His words then, doesn't it? Why not start with the ones he just repeated four, five, six times? "For my flesh is food indeed, and my blood is drink indeed"
v63 is not the equivalent of Jesus shouting "opposite!" like a fourth grader. It makes Jesus a liar. "This is my Body" is not at all the same as "this is kinda sorta like my Body"
