This seems reasonable explanation on first glance, but on further thinking it seems to miss something. Assume 'down arm' as leg, and 'up arm' as head, relative to the person who has the arm just like left and right arm. Even then the mirror doesn't flip up and down arm, but only flips left and right.
- hammock 6y agoagreed. As another commenter mentioned, what a mirror does is not flip left-right, but front-back. (notice front-back are still relative terms, so parent comment argument is moot)
