So having a floor scale... Weight before and after it's over rated...
47.5 in one session? those are rookie numbers
If i was a xenoscientist, and if we had contact with aliens, i'd rate them formost by the way they get rid of their bodily-waste. Our (western world) system is decent enough considering our limitations, but imagine what a alien race, that masterd space travel, could maybe come up with to get that waste removed/recyled!
Only works if your legs are short enough to be dangling over the floor...
Don't sit on the scale.. shit on it.
It's way easier that way I always shat on the scale.
