    Worked outdoors at a lumberyard, in Tucker for a year. Rode a bicycle to & from work. Sometimes couldn't believe I was getting paid to be that happy. Sunshine, fresh air & physical labor is quite the health elixir.

    I involuntarily took up the early to sleep, early to rise cycle in Peace Corps. After the Sun went down there was very little light, but during the day there was a hot tropical Sun in the sky that was hard to escape. I never felt so happy and healthy. I stayed, and despite now using more artificial lighting, I still go to sleep by 9 and get up around 5, even on the weekends. It's great, especially for my mental health.

    For many years I commuted to the city by bus , working in a nice but stuffy office , maybe walked to meetings a few blocks away and commuted back at night . I did not feel that good really . When I retired , I swam at the local beach sailed and walked and literally soaked up the sun , the body responded and was a lot happier. Far less colds and other bugs .

    As for the overnight....amber light idea "except when we have to do regular checks...or in an emergency". Does anyone actually think people get to sleep in a hospital?This reminds me of a Dr who came in at 7 & said open the blinds it's morning....as if the patient had been sleeping for 8 hours. I told him these poor patients are disturbed constantly for vital signs, lab draws...IV's beeping, medications, toileting.....& sleep is important too. Breakfast is at 8 & they need to sleep when ever they can between our disturbances. Sleep is more important than light when people are ill. But sure if they want to change the lightbulbs to something better that would be great.

    Yellow driving glasses also works, so in case you couldn't dim the light you could instead wear this glasses. They are very powerful tool, if you wear it during the day your whole day will feel like at late evening, regardless of even the heat & intense brightness of the noon.

    "I want to stay up late but my husband will not let me." "I have to get up (at 0500) to cook my husband breakfast..." I realise that they (the Amish) have a different way of life, but if one person in a relationship gets to dominate/oppress the other - GTF.

    1879 Thomas Edison is the most celebrated of incandescent inventors. He was able to succeed in creating the first reliable (therefore marketable) light bulb. His bulbs made after 1880 lasted a whopping 600 hours. He then hired lots of talented engineers and created the world's most famous "invention factory".

    Thomas Edison is to the incandescent light bulb what James Watt is to the steam engine. He did not _invent_ it (in fact there were more than 20 types of incandescent light bulb prior to Edison and Swan) he merely perfected it. As you pointed out, rather successfully making it the first commercially viable light bulb. The subsequent marketing of his bulb with his name is why he is often credited with its invention.

    Lovely Linda did mention that it wasn't so much electricity that the Amish had a problem with, rather the more intrusive aspects of modernity. They've probably just made a decision that on balance, keeping food cold is not causing any real harm and is simply a sensible way to reduce waste and potential disease etc.

    Yes plants give us oxygen and we give them carbon dioxide. We are not separate but different parts of the One that we are, just as male and female are different manifestations of the same thing. The bible is not literally word for word info, but metaphors. Eve was not created from atom, atom was male and female and they divided into two parts but neither part can exist without the other just as there can't be a right without a left. Two parts of the same One.
