The reason why the *overall* average shows women getting less is because there are simply fewer women willing to do high-paid jobs like programming, or dangerous high-pay jobs like living on an oil rig.
...or that the jobs that women traditionally do (teaching, nursing, etc) are valued a lot less by society. I never could understand why teachers are treated like crap in North America.
In fact, I can't actually remember the last time I saw a signature that was anything even remotely approaching legible. Distinctness is all that really matters.
My mom has a great signature -- very distinctive, consistent, and done quickly in one fluid motion. It is *really* hard to get just right, though I can get close. My dad's is dead easy to forge, especially since my writing is similar to his in the first place. So I spent a lot of time developing my own handwriting and signature when I was young, determined that noone would be able to forge mine too easily. All that practice meant my forgery skills were in demand in school when other kids couldn't fake a parent's note or signature.
Also: Apparently fancy private schools in the Philippines all teach their own distinctive kind of writing, so if you're in the know, you can tell where someone went to school just from their writing (and judge appropriately).
AND we're clogging the same system with trivial shit (of interest to archeologists, but worthless otherwise).
..of which there will be tons of, thanks to the Diaper Genie. It makes me laugh, thinking of the first archeologist who will happen upon these sausages of poop.
