Passive house ventilation
This dilution effect is particularly strong in the winter; cold outside air contains very little water vapor (with -5°C/90% e.g. only about 3 g per cubic meter of air, see first diagram at left). If this air is brought inside, it is eventually warmed up to 20 °C and then its relative humidity amounts to only 17.6% - as long as no additional water from internal sources of is supplied to the room air.

We Evolved to Run—But We're Doing It All Wrong
One of the things I love about running is that I don’t do it to get fit. Getting fit is a byproduct. What I like is time offline so I like my runs to be really relaxing, not frenetic. As soon as I am counting the time in which I’ve done the last mile, or checking to see how many steps I’ve done, it starts to be less relaxing. Nobody checks their calorie burn after an hour’s meditation. And for me, running is more like meditation than it is like keep fit.

The Science of Sport: Exercise and weight loss Part 3: Fat
Have read something similar before. It's very difficult to lose weight via exercise alone: "So, taking our 80kg man, who runs 8km (5 miles), he'll burn about 640 kcal. ... Now, assume that half his energy comes from fat and half from carbohydrates. That means 320 kCal from fat, corresponding to 35 g ... So, 35 g of fat in 8 km or 5 miles. To burn 1 kg of fat, he therefore has to run 230 km (142 miles). Not very encouraging."

If Health Care Is Going to Change, Dr. Brent James's Ideas Will Change It
"During one of our first conversations, Brent James told me a story that you wouldn’t necessarily expect to hear from a doctor. For most of human history, James explained, doctors have done more harm than good. Their treatments consisted of inducing vomiting or diarrhea and, most common of all, bleeding their patients. James, who is the chief quality officer at Intermountain Healthcare, a network of hospitals and clinics in Utah and Idaho that President Obama and others have described as a model for health reform, then rattled off a list of history books that told the fuller story. Sure enough, these books recount that from the time of Hippocrates into the 19th century, medicine made scant progress. “The amount of death and disease would be less,” Jacob Bigelow, a prominent doctor, said in 1835, “if all disease were left to itself.”"
