Does anyone know of a good life expectancy calculator? Preferably one which has good justification behind the model, and also has been tested.
I tried this calculator, but I noticed a few issues. First, it sells me I should start doing conditioning exercise... when I did check that off. I think that part of the calculator is broken. It also seems to think that taller people live longer, when from what I understand it's well accepted that the opposite is true. Some of its other features seem unjustified to me, for example, it seems to think you get a life expectancy boost from eating less than 10% of your calories from fat, but I can't find any evidence for that.
Good life expectancy calculators seem very valuable to those interested in longevity. Perhaps some people at LessWrong should create some sort of model. Though I have little experience with these sorts of statistical models, I think the Monte Carlo method might be useful here to get a distribution. If we put the code on GitHub then others can take a look at its guts and submit corrections/improvements/pull requests if they want to.
A good life expectancy calculator implies a good model of which factors drive longevity. I don't believe such a model exists (for healthy people -- the effects of various illnesses on your life expectancy are known much better). There are a lot of correlation studies but correlations and causality are not quite the same thing.

"Some sort of a model" is a very low bar -- presumably you would like the model to be good. People who will be able to make a good comprehensive model of ...
