The Poodwaddle Life Clock compiles the data of many health studies to build a life expectancy calculator. The questions it asks have all well documented effects on longevity and we believe the results are as accurate as reasonable possible.
The Life Clock displays a very accurate figure (down to the second), but this is not intended to imply a degree of certainty. Rather, our intention is to inspire the reader to value the time he has. Results are averages and should not be accepted as fact or fate. It is very unlikely that one will live exactly as long as we predict.
Every question we ask is based on a study - research, not conjecture. However, we were not able to ask every question that might impact life expectancy. We were limited by research availability and space. Please ask your doctor if you have specific health concerns.
The Life Clock shows four figures: age, real age, life span, and life expectancy.
Age is your Gregorian calendar time since birth (based on 365.25 days per year).
Real age is a bit of a misnomer. Technically it should be called "proportional age" since it is your life span proportional to other people of your region. We call it "real age" because we intend to convey that calendar age is not the most accurate way to measure your life. So, a 20 year old who smokes and doesn't wear his seat belt might have a real age of 35. His life is half over. But a 35 year old who eats healthy, exercises, and has no family history of cancer might have a real age of 20. Only 1/5th of his life has passed.
Life span is the total length of life from birth.
Life expectancy is the time remaining (life span - age). We calculate to the second only to inspire the reader to value his time, not to convey certainty.
