That's pretty much what I meant by evidence.
One could argue that third world countries have shorter life spans because of lack of health care.
It could also be lack of knowledge, lifestyle, infrastucture (water etc..) too many variables.

Not only do we need Data...Dr Beverly Crusher would be a help too!
