When I stay indoor long, I become immobile and stagnant, and not physically only.
Thoughts and thinking would become less free going and spotaneous.
Emotionally it gets more negative.
And most of all my spirit would be dimishing and less vibrant.
All in all, staying indoor for too long is a bad bad thing that everybody should try to avoid.
But how long is too long?
Staying home for a whole day would be too long for most people, in my opinion.
And doing that too often is definitely a bad thing for anybody physically as well as mentally and emotionally.
