busy, occupied, restless
忙 centers on a state of being fully engaged with tasks, leaving no room for rest: busy, occupied, or restless from constant activity.
忙 combines 忄 (heart/mind) with 亡, which likely contributes the sound and suggests a sense of being overwhelmed or lost in activity.
The heart radical 忄 beside 亡 (which can suggest loss or death) paints a picture of a heart so busy it feels lost or deadened by constant activity.
For ボウ, imagine a busy worker bowing repeatedly to everyone they rush past: bow -> ボウ, and the heart is too occupied to stop.
