Liquid Diet and jogging while on the cellphone

Dr. Lele from Roswell Park Cancer Institute said I can jog up until the operation this Wednesday, so I am. Usually do non-impact using elliptical trainer, but here in Buffalo I've had to return to street jogging. I fell while talking on the cellphone today. Great talking to others, makes the run go fast, but gotta watch out better. Sores on one knee and arm bled a bit, but I'll heal fine. Just trying to be in as good health as possible. Today is clear liquids only, all day until midnight; with 8 oz. of Magnesium Citrate midday and yuk.... stay near le toilet....
