Maintaining a house verses maintaining your bodily temple.
I've always considered it disgusting but it is showing up more and more often to me. What I am a referring to is the most purified liquid available, basically your own personal urine is a miracle cure and a highly valuable medicine, and may be liquid gold for health recovery. Mostly for drinking but also rubbed onto the skin for absorption.
Apparently from what I've heard is that even the sickest person can heal with their own no matter how disgusting it looks. The worlds most filtered substance is not a waste product, it is excess super super healing liquid that your body disposed of but can re-use much more efficiently the next time around. The second time around the body uses less resources to create the healing compounds it needs so the healing process is boosted.
There are many stories of survivors in the desert or even miners stuck down deep. It is something to think about if serious times of starvation come around, as people can survive longer if they re-use this miracle golden liquid produced from their own body instead of throwing it out. No, I haven't tried it, though the universe seems to be continuously revealing this secret to me.
