Time is life. How much "life" do you waste a day? Watching 1 hour of television every day for 40 years amounts to a total of 14,592 hours, which is equal to an extra 9 years of schooling. DEATHLINE is a to do list application equipped with a lifespan analysis function, enabling you to calculate how much "life" you actually put to waste. Your lifespan is derived from your heart rate based on the theory that the human heart can only beat a certain number of times in a lifetime. By entering daily tasks on the DEATHLINE to do list and recording how much time it takes to finish each task, you can find out how much "life" you are spending and how much more you will spend if you were to work on the task periodically for the rest of your remaining life. Use DEATHLINE to eliminate all the trivial factors in life so you can spend quality time on what really matters.
