How much of your life do you reckon you've spent sleeping?
Your answer is probably 'not enough' but if there's now a new website which will give you a slightly more accurate answer based on your age.
Just go to My Life Asleep and you'll be able to enter in your age. From there you'll be presented with some calculations breaking the time down into years, weeks and even hours.
That's not all though, the website will also calculate how much time you spent dreaming and about what topics whether it be money, falling or sex.
The site will also estimate the number of calories you would have burned in that time.
