It has been known for over a hundred years that serious medical conditions
affect life expectancy. Some of the more common conditions are:
- Hypertension, atherosclerosis, history of heart attacks
- Chronic obstructive pulmonary disease
- Cerebrovascular accidents (stroke)
- Chronic renal insufficiency
- Diabetes mellitus
Other negative factors for life expectancy include:
- Lifestyle: Smoking, alcoholism, drug abuse
- Education: High school education or less
However, there are also positive factors for life expectancy, such as:
- Lifestyle: Non-smoker, moderate use of alcohol
- Education: Bachelors degree or higher
- Religion: Mormon or Jehovah's Witness
- Being slightly below average weight
We have published peer-reviewed medical articles on life expectancy in many of these conditions, including:

It is desirable to take into account all major risk factors, both positive and negative.
This is possible using standard actuarial methods, together with information
from the medical literature.
