The consumption of water is part of it (scientifically).
So is fitness and nutrition, actually all aspects of the human body can be regulated by using the mind and following the outline for the ‘Wheel Of Life’.
We need awareness and the will to carry it out.
It is like a miracle, once we see it and love it, it will grow in proportion to our effort to actualize it.
Yet, good and bad, we can make it manifest.
There is no time or space in the imagination.
It just is.
It is our choice to grow and thrive and put the effort forward to make manifest in our lives all we hold dear and true.
In this sense, we are forever young.
In this sense, our lives are constantly renewing our youth until we spend it all or use up our life.
It is a shame to be left wanting as this life, no matter how long or brief, is the ultimate gift.
Enjoy.
