depressing thought for the day

in the final analysis, all your hopes, dreams, and thoughts are nothing more than the means of processing sensory input that was selected by nature to most likely result in reproduction. any further purpose is a construct of your imagination, perhaps useful to survival, perhaps not. so go out there, achieve! strive for excellence! and if you're feeling down, cheer up! your troubles are nothing compared to the inky black pit of despair that will engulf humanity during the final stages of the inevitable heat death of the universe. the star in our last habitable planetary system will eventually burn out, and our last remnants will turn on each other like savages in the desperate fight for food and heat. the last living human will look through frost covered windows at the wreckage of our civilization, eat his last candy bar, and wait for the bitter end.
