There is an exercise that you often read about that you can use to conceptualise your weight lose - the one were you go to the supermarket or somewhere and get a bag of spuds or some tubs of lard or whatever equal to the amount you've lost and try to lift them.

I've always thought that was a big hokey myself. Then tonight I bought a new computer chair. It was so heavy. I had to drag it in from the car (it was unassembled otherwise I could have wheeled it in, damnit) then drag it to my room. My poor little arms were aching and my back was killing me. I thought I was going to die.

When I got it inside I noticed something on the box. The chair weighs 16.3 kilograms. That is just a little less than I have lost off my body. I used to carry a damn computer chair around on me!

Sure that 16.3 kilos were evenly(ish) distributed around my body so it wasn't like my puny arms were taking the brunt of the weight but it is still a damn lot to haul around. And, to be honest, I'd much rather have my computer chair under my arse than on it.
