I personally have a tough time filtering out inputs, and find my attention forcibly split between paying attention to nearly everything whether I want to or not. This makes me act and plan more linearly than is optimal, and is horrible for crowded rooms, but otherwise doesn't disable me. Also, I have a strong dislike of the action of chewing gum. I was recently joking about not being able to walk and chew gum at the same time, and I wonder if it might actually have some truth to it? I would like to know everyone's (but especially people with similar filtering issues) habits regarding gum.
How often do you chew gum?
(The poll is in the first comment.)
Smoking isn't very rational. That's why some people here who've never smoked chew the gum instead.
Do you mean going from not smoking at all, to chewing nicotine gum? I find that tempting, along with electronic cigarettes, because of the upsides to nicotine. It still seems like a bad idea in the long run due to withdrawal effects in the event that nicotine was unavailable.
