I think Henry David Thoreau's book "Walden or Life In The Woods" has some numbers and calculations of Thoreau's self-sufficiency experiment - like equating time spent and the yield for different tasks. (I don't remember exactly, it is something like twenty years since I read the book). Oh well, but maybe I could do something like that, too. Writing a blog post just counting time spent (and distance travelled) picking berries, and recording the amount of harvest, also calculating the nutritional values etc.

But, yeah, my general approach to life has always been less calculative as I greatly value qualities which aren't that easy to measure (like, time spent in forest has good effects on mental and physical well-being, and those effects aren't easily counted. There already is scientific data showing the effects are real, but I don't know if there already is research showing if it one's state of mind makes a difference - like, if one hurries to get as much berries gathered as quick as possible, does inhaling forest air have all the good effects it does when you go stroll in the woods mostly to relax?)

Hehe, and anyhow - if there are any scientists (or persons who make decisions on science funding), please consider adding more research in the health benefits of nature. My hypothesis is that plants might be emitting some pheromones which the human system takes as anti-stress signals.

Sorry for sidetracking =) I mean, I'm totally with you with the dislike of buying food packed in plastic !
