Focus your last thoughts on the most profound thing you can think of.

You focus your mind like a laser and concentrate hard on thinking of the most phenomenal, fascinating and interesting things you can come up with before your blood deprived brain completely ceases functioning.

Depressingly, all that your dying brain can produce in your final waking minutes is the word "Kill" and the concept that at this point it would probably be rather hard to act upon the word "kill." How upsetting.
