体 (traditional 體) was radically simplified into one of the loveliest new characters: person 亻 + root 本 — the body as a person's root. The traditional form needed 23 strokes of bones and ritual vessels; the simplified needs 7 and says more.
体 embodies: 身体 (body), 体育 (physical education — 'body cultivation', every schoolchild's favorite class), 字体 (font — characters have bodies too!), 体验 (to experience — test with the body). 体面 is dignity: 'body-face'. When Chinese asks 体验一下? ('want to experience it?') it invites your whole body, not just your opinion.
A person's 亻 root 本 — the BODY.
字体 'character body' = font. In Chinese, even typography is anatomy.
