A method for operating an electronic system to monitor a health characteristic of a user based on one or more biological measurements, comprising: determining a current context of the user based on at least one context measurement provided by at least one context sensor, wherein the context measurement comprises at least one of activity information, health information, weather information, time information, or space time information indicating where the user is currently located; selecting a context record corresponding to the determined current context of the user from a plurality of stored context records, wherein each of the plurality of stored contexts is associated with a user-specific baseline value of a health characteristic of the user ,and monitoring the health characteristic of the user based on one or more bio-sensing measurements received from one or more sensors in comparison to the user-specific baseline value corresponding to the selected context record, wherein the monitoring the health characteristic of the user comprises: detecting a first event corresponding to the health characteristic of the user being at a first level; detecting a second event corresponding to the health characteristic of the user being a second level, the second level being different from the first level; determining a health-resiliency measurement based on an amount of time between the first event and the second event; and monitoring the health characteristic of the user based on the determined health-resiliency measurement. determining a current context of the user based on at least one context measurement provided by at least one context sensor, wherein the context measurement comprises at least one of activity information, health information, weather information, time information, or space time information indicating where the user is currently located; selecting a context record corresponding to the determined current context of the user from a plurality of stored context records, wherein each of the plurality of stored contexts is associated with a user-specific baseline value of a health characteristic of the user ,and monitoring the health characteristic of the user based on one or more bio-sensing measurements received from one or more sensors in comparison to the user-specific baseline value corresponding to the selected context record, wherein the monitoring the health characteristic of the user comprises: detecting a first event corresponding to the health characteristic of the user being at a first level; detecting a second event corresponding to the health characteristic of the user being a second level, the second level being different from the first level; determining a health-resiliency measurement based on an amount of time between the first event and the second event; and monitoring the health characteristic of the user based on the determined health-resiliency measurement. detecting a first event corresponding to the health characteristic of the user being at a first level; detecting a second event corresponding to the health characteristic of the user being a second level, the second level being different from the first level; determining a health-resiliency measurement based on an amount of time between the first event and the second event; and monitoring the health characteristic of the user based on the determined health-resiliency measurement. <EOS>
