Abstract
The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Efficient systems for tracking age-related biol ogical degradations suffer from difficulties in adequately sampling the breadth of physiological parameters that relate to degradation over the lifetime of the user. Furthermore systems encounter difficulty in efficiently and properly ident ifying the ways in which degradations occur, capturing the amounts of degradatio n and rates of degradation, and predicting degradation trajectories from these c onfounding variables.”
