### Astrology

I've been debating my friend on the truth or myth of astrology. My stance is that it's a load of horse crap but I'm having difficulty actually convincing her of that. I use arguments like how the procession of the earth means that our zodiac signs (by her metric, I know that some schools actually us...

### Re: Calorific value of the typical person

Well, if you know what their body fat % is and how much of the rest of their body is inedible (unless you're looking for the calorie count on those parts too), I'd imagine you could just figure it out by mass. ~3500 kcal is 1 lb of fat, or 9kcal to 1g of fat. 4kcal to 1g of protein or carbohydrate.
