Sound Eating and Light Eating for Health
Research shows that mice even with a small amount of light (like a small TV's worth) while they sleep gained about 12 grams of fat while those without the light gained just 8 grams. (But what mice smoke in laboratory research?) No need to put a wall of light in your kitchen if other science shows merely painting the walls the right hue helps to lose fat.
It's been found that people in noisy sleep environments have an increase in blood pressure even while asleep and even for hours after the noise is stopped. Noise worldwide is estimated to be the cause of 100,000 deaths a year by raising blood pressure. This leads to the interesting question of noise and weight, if noise makes people or mice gain weight. If so there may be legal questions like in the Mcdonalds this year in Brazil that's awarding 75,000 to an employee who said they had mystery customers (he saw them in the light no doubt so he claimed he had to eat to stay healthy in business, winning the lawsuit.). Mcdonalds said they offered health alternatives for the Franchise owner but in the trial this was refuted. The answer to the obesity epidemic might thus be to merely put on antinoise headphones, and employers might indeed get much higher productivity as research also shows that conversationl distractions cause double the reduction of employee efficiency, thus cheap viable antinoise may be a major step forward for billions of people, a side order of cheeze for a rich inventor!
