"Here is what we know from a scientific point of view: There is no amount of wood smoke that is good to breathe. It is at least as bad for you as cigarette smoke, and probably much worse. (One study found it to be 30 times more potent a carcinogen.) The smoke from an ordinary wood fire contains hundreds of compounds known to be carcinogenic, mutagenic, teratogenic, and irritating to the respiratory system. Most of the particles generated by burning wood are smaller than one micron—a size believed to be most damaging to our lungs. In fact, these particles are so fine that they can evade our mucociliary defenses and travel directly into the bloodstream, posing a risk to the heart. Particles this size also resist gravitational settling, remaining airborne for weeks at a time."

"Now, a century after psychologists first came up with the idea of “general intelligence”, the world’s biggest study of its kind has put paid to the simplistic idea that we can use an IQ figure to describe the astonishing abilities of the human brain."
"Regular brain training didn’t aid performance at all, yet people who often played other types of computer games did significantly better in terms of both reasoning and short-term memory. It seems the popular idea that brain-training games are helpful whereas standard computer games are somehow bad for us could be the wrong way around."
