This calculator was adapted from Project Big Life (Canadian research) and its use was permitted by the developers. Please note that the values are not exact and for illustrative purposes only. Important factors, such as your socioeconomic surroundings or genetical factors are not considered and may be miscalibrated for populations outside Canada, for which the original model was developed. The calculator is based on a statistical model and cannot calculate sensible results for extreme inputs.
