Snow
Try going outside when there is a lot of snow; particularily if it is still snowing. Do some excerise like sledding or shoveling. Then, find a nice snow bank and just flop down into it. Lay there quietly. If you are in the city this wont work so much for you. After flopping down relax your body. The snow muffles all sound. It is silent; all you can hear is the steady fall of flakes onto the already piling snow. Look up into the sky and watch the flakes fall down onto your face. You feel like you could stay there forever in that spot. For a few precious seconds of your life you have no responsibilities, no concerns, hopes, emotions, stress, pain, nothing. You stop thinking. You want to never ever get up again. But then the cold and wetness seeps into your clothes and the snow falling on your face hurts and freezes and you are welcomed back into the world with discomfort and cold.
