You are missing the point of the garage story.
The point is that one hour of exposure to tobacco smoke in a bar or restaurant is no where near as deadly to a person with no pre-existing health issues as is exposure to automobile exhaust.
The entire point is that it is a matter of choice as to which place you wish to enter.
I didn't miss the point. I agreed with you & even gave another example of something that was worse than cigarette smoke. Good grief, you people are so hard to get along with. Gripe gripe gripe I try to be friends & all I get is an argument. Good bye! %;9}
