Big problems:

1. Too much time indoors, not enough time outdoors. For example, in modern day times we almost got *too much* time to think! Too much thinking is bad. The purpose of man ain’t to think — technically we are beasts just like any other animal out there. However it is our higher-order thinking which *distinguishes* us from other mere beasts.
2. We spend 8-12 hours a day indoors,,, maybe even more? At work, in the office ,,, all indoors! Then you drive back home (stuck in traffic ,,, maybe another 2 hours a day in the car). Then you eat cook food at home,,, more time indoors, you sleep indoors. Wait — when does the average human being have the chance to spend *any* time outdoors?
