"Girls, Boys, and Media: A Gender and Digital Life Toolkit for Educators Messages about gender roles come from all directions, but some of the most influential messages come from the media. For today's kids, that means not just the TV shows, movies, and ads they see, but all of the messages and images they create and receive from their friends. Use this toolkit to help students reflect on gender stereotypes: where they come from, how we learn them, and how they can shape the media that we consume and create."

Very good video on how the messages girls get about beauty from the media.

"It's just gym, huh? Well think again. It's the only subject I know of that directly reduces a kid's long-term risk of heart failure, diabetes, depression, anxiety, several cancers, and obesity - and at the same time enhances fitness, cognitive function, self-esteem, teamwork, and overall good health. Like it or not, the truth is, if we keep cutting PE out of our schools and physical activity out of our lives, America's next generation will be dying at younger ages; losing its competitive edge; finding itself displaced on the world's stage; and bearing the physical, emotional, and financial burden of obesity and chronic disease for years to come."

Aerobic training effects on power/strength output and body fat loss.

Really interesting and convincing video on how we are not actually getting bigger, stronger, faster.

"Worldwide, we estimate that physical inactivity causes 6% (ranging from 3·2% in southeast Asia to 7·8% in the eastern Mediterranean region) of the burden of disease from coronary heart disease, 7% (3·9-9·6) of type 2 diabetes, 10% (5·6-14·1) of breast cancer, and 10% (5·7-13·8) of colon cancer. Inactivity causes 9% (range 5·1-12·5) of premature mortality, or more than 5·3 million of the 57 million deaths that occurred worldwide in 2008. If inactivity were not eliminated, but decreased instead by 10% or 25%, more than 533 000 and more than 1·3 million deaths, respectively, could be averted every year. We estimated that elimination of physical inactivity would increase the life expectancy of the world's population by 0·68 (range 0·41-0·95) years. "

Thanks for sharing, Thomas!
