Bicycles and walkable neighborhoods

I ride bikes, I used to race bikes, They are the greatest local transportation. They can get you out 10 miles or even more, they're great exercise, reduce air pollution. They can help us solve our diabetes crisis and air pollution. When there are paths for bicycles they are used from what I have seen. Bicycle commuting makes up less than one percent of commuting so it really is trivial, but when there are trails people really do ride to get places on them so we need to build more. And people must want these because houses are more expensive in areas with bicycle trails, so there aren't enough. I find it ironic that when there is a bicycle trail the house prices go up so much because then only wealthier people can afford to live close enough to a trail to save money riding a bicycle instead of driving. Actually neighborhoods with trails for bicycling or walking can be so much more expensive than other neighborhoods it negates the cost savings so we really need to make more so these neighborhoods become affordable.

Look whats going on in Salt Lake City where I used to live: https://www.google.com/search?q=salt+lake+city+air+pollution&hl=en&client=firefox-a&hs=XBL&tbo=u&rls=org.mozilla:en-US:official&tbm=isch&source=univ&sa=X&ei=kCgNUY_6DMbX0QGCuYCoAg&ved=0CEEQsAQ&biw=1525&bih=690


Or worse in Beijing: https://www.google.com/search?q=beijing+air+pollution&hl=en&client=firefox-a&hs=zCL&tbo=u&rls=org.mozilla:en-US:official&tbm=isch&source=univ&sa=X&ei=6igNUePqAsu30gGly4DwCA&ved=0CEwQsAQ&biw=1525&bih=690

This bicycle even gets power from the brakes to use for going up a hill: http://senseable.mit.edu/copenhagenwheel/. Since it's not the Tour de France we are allowed performance enhancing technology.

Most efficient ways to build fitness

Some of the most efficient ways to exercise are weight lifting about 24 repetitions of each exercise to complete exhaustion and interval training like some kind of sprinting. Lower weight higher repetition weight lifting (meaning about 24 reps) done to complete muscle exhaustion (lift until you can't lift a single time more) can actually build muscle even faster low repetition with a heavier weight. A study on this is here: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0012033 N. A. Burd, et al. “Low-Load High Volume Resistance Exercise Stimulates Muscle Protein Synthesis More Than High-Load Low Volume Resistance Exercise in Young Men,” PLoS ONE, vol. 5, no. 8, p. e12033, 2010. Interval training works so well partly because you move fast turning on more fibers. Each muscle fiber in a skeletal muscle either contracts fully or not at all. You lift heavier weights or move faster by contracting/engaging more muscle fibers. So fast motions in interval training

Air pollution, diabetes, global warming - same problem

Air pollution, diabetes, global warming  and are highly related problems. Much of our air pollution comes from how much we drive everywhere. This air pollution includes CO2 driving global warming. Our traffic clogged streets and towns make it hazardous to walk so we don't walk and we put on weight and develop diabetes. I am a die hard cyclist and walk commuter and live right by a shopping center that I can see from my apartment but even I never cycle or walk there because the entire center is a parking lot and I would probably get ran over. If we rebuilt are towns and cities for walking we would walk more, reduce air pollution, global warming and diabetes all at the same time.

Academy and industry growing the science pie

Like anyone who has worked in the commercial biotechnology science industry I have also spent time in academic science research in graduate school. There is definitely some rift between the two worlds of science. I find industry often doesn't know what is going on in nearby academic science centers, and academic science centers often don't want them to know because they think industry will steal their ideas just when they start working (There could be some truth to this.). The two science worlds should work closer together to grow the science pie. The government invests in academic research to improve health, improve the environment, improve lives and stimulate the economy and stimulating the economy is getting top billing now. Government investment is a fixed amount allocated each year. Academic scientists write grants to compete for their share of the pie. When one scientist wins another loses. Industry starts with basic science and applies it to problems (like diseases) to
