Now there's an infinitely-answerable question! I don't think bout what would happen if my pineal gland turned into trifle, or the implications of the increasing variety of hair-care products on Afro-Vietnamese relations, or how many M&Ms it would take to fill my shoe (though I admit that the latter question could well turn up in one of these trendy job-interviews we keep hearing about - get researching!)
Basically, I don't think about those things (in any depth, at least) because nobody else does. Subjects such as the double-edged sword of nationalism etc. plague our collective consciousness and as such are worth the brain-cycles, if you're that way inclined.
