The medieval Islamic physician Ibn Sina — known in the West as Avicenna — argued in his Canon of Medicine that the body and mind share a single 'vital spirit,' and that prolonged anxiety physically degrades what he called the 'animal faculties': perception, memory, and judgment. This wasn't metaphor. He was describing, in 11th-century terms, what neuroscientist Bruce McEwen would later formalize as allostatic load — the cumulative physiological cost of sustained stress. Both men reached the same conclusion from opposite directions: recovery isn't the absence of effort, it's the active preservation of capacity. The leader who treats rest as weakness is running down the very instrument they depend on. What you protect today determines what you can deploy tomorrow.

Name one recovery practice you've cut short this week in the name of productivity — and be specific about what decision or interaction may have suffered as a result.
