I didn't misquote you, I just didn't feel like quoting every line of your post, otherwise I was aware of which parts were about Se role just fine. When I indicated his response was actually Se, I meant that it seemed Se in ego if that's what threw you off.
Yes as I said I agree he must be xLE.
His answer to the health question did not seem like unaware Si DS, honestly. He explicitly says he pays attention to himself. He knows what it means to let the body take care of things. (Though I don't know if he takes it to the extreme too much with not taking medication. But if he just meant he doesn't pop a pill for every little thing then I totally get his reasoning.)
Anyway will see OP's answers first before I say more.
