what is the proper ph (urine)?

[Zaphirah]

I'm trying to find out what the proper ph for urine should be...I found one (not so reliable) source that said 6.6. does that sound right?

According to the pH Miracle Diet by Robert Young, we should be aiming to get our urine to an alkaline state above 7. You can do this by adding lots of greens, and adding pH drops and green powder to ALL your water, making it alkaline.
