Ergonomics, Shmerganomics

Ergonomic standards are for human bodies that are pretty standard. I'm taller than average, with arms that are long for my height. I do not fit the average set up for a sewing work surface.

When seated like shown in the picture? There is barely room above my knees for a table.

Where the words "knee angle" are? Nope. The table fills the space when it's me sitting there. My elbows aren't somewhere at the bra line. My elbows are right at the top of my hip bone.

This may be why I sew with my shoulders up by my ears.
