Do you actually get 6 hours of sleep every night? I don't ... wonder how soon I will die... I usually sleep 5 to 6 hours during the week and may be 7 hours on the weekend.
Let's see, if you sleep 2 hours less everyday. For 25 years, there are 18,250 extra hours, that is equivalent to an extra three years in your life (for 24-8 hrs a day). With the odds of 12%, it is a sure bet. What's the point of to be alive, if you are sleeping.
