34 minutes is good. More is better, if you have the time. Or we can MAKE the time.

As far as Yin Yang water I know there are topics about this here on the SFQ forum that will answer your question.
Basically it is a glass of water. Half spring or regular cool water and half boiling water and a tablespoon of honey. The two types of water have the different energies and honey which is powerful because of all the flowers the bees must visit to create it.
I drink it regularly and it works.
Take care.
