I want to find out how to quantify various lifestyles factors on
lifespan.  I would like to find out where I can get answers to
questions like:
1.  How much longer will your life be if you are 40 (for example) and
you don't smoke versus a person who does smoke?  The answer is in
years.
2.  How much longer will your life be if you wear seat belts versus a
person who doesn't wear seatbelts??
3.  How much longer will your life be if you don't fly versus a person
who flies 100,000 miles per year.
4.  How about the regular exercisers versus the coach potatoes?
5.  Any other similar topics.
I am planning a speech on what you can and can't do to increase your
life expectancy within the everyday good and bad and necessary habits
that all of us have.
