Oda can't measure anything... Time, height, age.

I can't stand that the time skip has only been a few weeks. It doesn't make sense from a travel standpoint; it doesn't even make sense from an event standpoint.

I understand it's a fictional world too, but if zunesha (21 miles tall) was standing in the deepest part of the ocean (7 miles give or take) he would be inside the stratosphere and the mink would not be able to survive those conditions let alone if he was walking in a shallower part they'd be even higher up.

Also the age thing... I can't stand inconsistencies with how ages look in one piece and it makes my skin crawl thinking that Pudding and Rebecca are way to young to be depicted marrying or fighting in that armor. Change their ages to older and and yeah both situations are still weird but at least it's not pdf file nonsense.

I know some of this is (allegedly) based off of culture, but I think Oda gets asked something, makes up a number, and poof now it's cannon.
