It's pretty easy to find documentation that documents persons who are seriously mentally ill or seriously physically handicapped have a shortened average lifespan .... but that can be said about many conditions. So what? WHY is this category so qualitatively different or substantially related to the concept of life expectancy that it warrants special notice when other genetic and acquired medical illness do not? That section should be removed in my opinion. I would be happy to post the underlying citations in an appropriate location in Wikipedia, just not here.
