No. Never, unless the doctor does it, and that is just for his stuff. I have a good, strong leather belt, and by the belt holes I can tell if I am losing, gaining, or staying the same in inches - at least around the waist. Between monthly water weight (if you know what I mean) and daily fluctuations and all, I just couldn't give a sh** about that particular number.
However, when I actually get around to the fitness portion of the PB, knowing the numbers on reps, or distance, or speed, or strength and such will be interesting to me. At least until I get honestly globally fit - then I won't care much about those numbers anymore, as I plan on then just having awesome fun keeping active and exploring stuff with my future fit body.
I have a mantra that I have spouted for years... "If I eat right, I feel right. If I feel right, I exercise right. If I exercise right, I think right. If I think right, I eat right..." Phil-SC
