Are you sure this person is an SEI? My understanding is SEI is Si base, so wouldn't they likely be health conscious and taking the steps towards improving their health? Maybe not every SEI but I think they would be more likely to than someone with lower order SEI.

I guess it just puzzles me why the person won't get treated if he knows its going to significantly shorten his life span. Doesn't like his doctor? He can always get a new one.

It makes me wonder if there is some underlying depression or something else going on.
