A good balance starts with mapping the risk: identify the threats to the mind—stress, misinformation, isolation—and to the body—intrusion, physical harm, data leaks. Then layer defenses: set clear boundaries, create routines that reinforce calm, and deploy concrete measures like encryption, access control, and safe physical spaces. Keep the systems simple, redundant, and always test them. A well‑guarded mind feels as secure as a fortified building.
