The Edge of the Cliff

The human body seems to come equipped with a natural radar for death-inducing situations. Standing that close to the edge of a cliff induces a heady sense of vertigo and threatens to regurgitate any recent meal. In various forms of Buddhism, the practice of meditation is often taught as preparing oneself for death while still remaining alive. The Stoics of ancient Greece implored people to keep death in mind at all times so they can appreciate life more.
