You can put the human mind and body into strange states through the use of alien environments.

The human body when kept in an indoor environment of low lux light will not realize that it is daytime, as it cannot sense the increasing levels of daylight that the genetics are accustomed to. As such, by late morning your body may start sending a signal for you to sleep!

I am not a fan of sealed up sterile homes or Faraday cages and their use in human health, although I do understand that some people do feel relief in these environments.

It is my conclusion that the human mind and body is essentially a single cell rechargeable battery that is charged from the atmospheric DC voltage and the Earth.

The human body is not designed to be sedentary.

Once the body has atrophied, you will become vulnerable to many conditions.
