I think I am beginning to notice this as a definite trend in my thinking. The way I think about food allergies works more or less the same way: I don't think about the probability of death so much as the possibility, without weighting. Unfortunate, perhaps, (particularly socially) but it's kept me from having to deal with anaphylactic shock so far.
Went to an Amazon info session. Totally contentless! But I got a shirt. One more day without doing laundry, whee.
Finally, I got some physics homework done and printed out the application for PGSS TAness.
