My weight and measurements ..

Not too sure weather this is under the right catagory, but I have just been looking through success stories and have looked at peoples measurements and weight etc at start and finish. I have noticed for a couple of people I looked at they had basically exactly the same measurements as me (maybe 1-2 inches different at the most) but they weighed a lot different to me, the most was 80lbs lighter :noway: . Im guessing its because everybody is different ?? just making sure as found this strange !! :ohwell:
