also, weight per can in 2010 (12g) is displayed higher then the weight per can in 1980 (19g)? but at this point I don't even think I can trust the can weights... is that really from Bill Gates? Very deceiving article...
They are pictured on a set of scales. A heavy can will depress the scales more and be lower.
People seem to be trying to go out of their way to read deception into Gates' article. Can't we accept it as slightly fuzzy figures, just like all real world figures are?
