I'm a lumberjack am I OK?

In Norway we burn wood in the winter to heat our houses. We have electricity as well but the wood burning stove adds heat with character. You can buy wood from local farmers but real men chop their own trees down and that's what I've been doing recently. Actually I'm not cutting trees down I'm sawing trees up, splitting the logs then stacking the pieces so that it dries out. The traditional way is to make a free standing wood pile but I'm not very good at it so pile mine next to the house. Different types of wood have different energy densities. Different types of wood have different energy densities, the favourite wood to use in Norway is Birch. Everyone says this is the best but actually it's only number 8 on the top 20 lists of energy density. They say that wood heats 3 times (I think). Once when you chop down the tree, once when you saw the logs and once when you burn it. My wood also heated me when I carried it from the forest and then again when I carried it to the house. I've made a problem sheet about my wood pile, here.
