You deserve a medal for having outlined the first challenge to fiscal survival for those of us of a retried disposition: how to calculate the perfect ratio, rate of use of resources available to survival time expected where the latter factor is the unknown? I've tried all manner of experiments with baths, taps of different diameters, pumps of different horsepowers, but nothing comes close to providing a definitive formula that works.
Even Einstein didn't manage to crack it; he avoided the question and looked elsewhere instead. Chicken!
