Lifelogging is the practice of recording a person's experiences and opinions in a comprehensive multimedia diary form. Such a diary can include audiovisual recordings of the events experienced by the lifelogger, as well as a detailed commentary by them on those events, and on any other subject matter that interests them.
Increased access to data recording technology made lifelogging popular from the Information Age onwards, and dedicated lifeloggers would use continuously recording equipment to record everything they saw or heard, although these recordings were sometimes at variance with the personal memories of that individual.
Lifelogging was often used in the creation of the first character simms, an early attempt at uploading a human personality into electronic form. The first character simms were crude and unconvincing, but over time they improved considerably. When lifelogging records were combined with direct neural interfacing and external memory banks in the Interplanetary Age the character simm evolved into the evocation, a form of personality capture that was far more accurate. But many researchers interested in the technology of immortality were dissatisfied with both character sims and evocations, since they were both methods of creating personalities that resembled the original, rather than true copies.
Later the technology of destructive uploading was developed, allowing for the first time the creation of true electronic copies of an original person. Copying did not become widespread until non-destructive uploading was developed in the First Federation era.
The creation of lifelogs with various degrees of detail is still quite widespread in the current era. Today a lifelogger can include an edited version of their sensory experiences and sometimes even their internal thoughts, although most lifeloggers prefer to keep the majority of their internal monologue private. Some lifeloggers broadcast or narrowcast their experiences immediately to an audience via the Known Net, often with a very small or non-existent audience.
Metamortalists and other persons who prefer to be remembered by their artistic or cultural output (rather than by recording their mind-state directly as a backup) often use lifelogging to increase the quantity and quality of that record.
Immortalist - Text by M. Alan Kazlev; amended by Stephen Inniss A sophont who aspires to attain physical immortality through indefinite perpetuation of a biological, technological or cyborg body, or software equivalent. This involves various preservation and renewal measures, including intelligence modification such as life-memory archiving. Most immortalists end up losing their personal identity after a few thousand years at most.
Immortality - Text by M. Alan Kazlev While literal physical immortality remains a contentious point in a universe that, although vast, is still finite, the wonders of modern medical nano mean that all citizens of the Civilized Galaxy, to say nothing of the higher toposophic ai, are potentially immortal; at least on angelnetted worlds.

Memory Storage, Long-Term - Text by Steve Bowers Memory storage for posthumans thousands of years old is often a problem. One popular (but clumsy) solution among some clades is to employ computronium implants, or even a small drone floating about for all the very-long-term memory storage. More elegant solutions involve a nanosome in each posthuman cell writing memory directly to redundant or specially set aside nuclear DNA.
