Calculate how long you'll live

Want to know how long you'll live? How about an optimistic guesstimate? Consumer Boomer has been blogging about life expectancy calculator Virtual Age; specifically how the online tool is quite generous with the predictions. After answering 35 questions about family history, exercise, diet and the like, Virtual Age estimated the CB blogger would live to be 97. After I answered the questions, Virtual Age said I'd live to be 99.6. Holy cow. Do I want to live that long? Anyway, let us or CB know if there's a more reliable life expectancy calculator out there.
