we must step on the same scale one day, I refuse to believe I'm
only 2.5kg heavier than you. 
Dude, I've verified my weight multiple times....
The most recent being my medical checkup last Saturday.
Yeah, some people don't believe that I'm over 60 kg, but really,
I am.
I've got a feeling that my bones are accounting for the extra
mass.... high-impact activities (e.g. running) does promote the
deposition of calcium on one's bones, and I do drink a lot of
milk....
