Not following you. a 45 year old uninsured smoker with lung cancer does cost more than a healthy person. Why do you think life insurance cost more for a person who smokes? Diabetes cost our health care systems loads of money. Obesity is a leading cause of diabetes. I'm sorry I may be misunderstanding your question.
Fatties and smokers have been proven to directly cost money.

Please at least not pretend that stuffing oneself with bad food and nicotine is a healthy lifestyle.
No one is "picking" on obese or diabetics. 2nd hand smoke illnesses is not some thing people made up to support their ideas or point the finger at, it cause cancer. Period.
