MNLifeAgent: Your "research" is unfounded and based on an assumption the members of the JWs are similar to members of other religions but have better morals/habits which equals better health.
An insurance company would never consider JWs a good choice. Why?
The typical JW lacks any form of higher education (i.e. university or college) as this is discouraged. Therefore they typically hold menial jobs such as window washing, cleaning and laboring. (No offence meant to anyone in those industries, unless you are a JW.)

Reasearch for yourself the link between higher education and life expectancy in the USA and you will find that those with higher education live on average 8 years longer than those who don't. This means JWs die 8 years earlier than members in comparative religions.
For JWs - your god jehovah always knew that you would die earlier because of your lack of education. This also means your service to the Watchtower will be on average 8 years less than if you received higher education. 8 years less preaching. 8 years less donations to the Watchtower coupled with lower donations because of lower average salary.

On the other hand the world doesn't have to put up with your nonsense more than they should. 8 years less. Actually, come to think of it, we should all thank jehovah god that JWs are less educated. 8 years worth of thanks.
Here are some links which compare life expectancy:
