From the literature I have read from DAN (divers alert network), the only pilots that ever even came close to being bent are those people flying U2s, SR 71's and similar aircraft, and they only "showed symptoms" of DCI.

Do not confuse nitrogen narcosis (getting "narked") with being DCI (decompression illness, also includes lung over expansion injury) they are not the same thing, and aren't really related.

I could write 1000 words about DCI, but you won't need to worry about it at flight level 350.
