vintage urine, enemas

Hi,First post. Using UT for a fortnight, one cup in the morning with juice.Saving all my urine for skin use ,burns, hair,and the apple & pear trees in the future.
My question is:
part a;what qualifies as old urine,is this used for ears,nose etc?
part b;can I use this older stuff as an enema. apart from type 2 diabetes for 11 years, I am reasonably healthy,BMI of about 30,coming down at 2 pounds a week.

thanks.riv
