1. A system for administering devices, the system comprising: means for receiving a plurality of disparate metrics for a plurality of users, wherein each user metric for a user represents an indication of that user's physical condition, wherein each user is a person; means for creating a first user metric vector comprising a plurality of disparate metrics for a first user; means for creating a second user metric vector comprising a plurality of disparate metrics for a second user; means for creating a first user metric space comprising a plurality of first user metric ranges; means for creating a second user metric space comprising a plurality of second user metric ranges; means for creating a mutual metric space in dependence upon the first user metric space and the second user metric space; means for determining whether the first user vector is outside the mutual metric space; if the first user metric vector is outside the mutual metric space, means for identifying an action, wherein the action administers a device to alter the physical condition of at least one of the users; and means for executing the identified action.
