Baptism Impossible Or Necessary in Cases of Poor Health?

A person with extraordinary health conditions is expected to be fully immersed, even if they use a breathing tube or have a permanent hole in their throat.  

In some “extreme” cases (as if the  “extraordinary” cases weren’t extreme enough) then baptism may be impossible “for the time being”,  in which case   “we can be confident Jehovah will regard the situation mercifully.”

-Watchtower, May 1, 1979

You will see in other more recent quotes that Watchtower teaches only baptized Jehovah’s Witnesses will survive Jehovah’s day. 

Also of note is that in the Watchtower, June 1, 2002, this article is mostly repeated but with the second part (pic 2 above) missing.
