Gobi asked:

Why is urine hot or warm when you excrete it?

Answer

Itís been stored in your body which is that fantastic body temperature of 37 degrees.  Itís like keeping something in an incubator, itís nice and warm.  When it comes out, itís still warm.  Because your skin is cooled by the air, anything at 37 degrees feels hot against your skin.  Youíll notice this if you put your hand in some water that is 37 degrees, it doesnít feel the same.  It feels warmer than blood heat.
