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.)
That I find interesting. Smoking is not very rational; it rides along with many social yearnings which I thought were somewhat rare here. (I also used to smoke cigarettes, but quit cold turkey, after about 75 failed attempts.)
Smoking isn't very rational. That's why some people here who've never smoked chew the gum instead.
