prematurely aged cells.

enfold aging cell parts into vesicles where they can be broken down and recycled, evolution has also put this mechanism to work in controlling fat, or lipid, levels and as a backup system for removing harmful bacteria.
Award supports research into how diet could take aim
at aging cells - USC Leonard Davis School of Gerontology

replacing aging cells with new, lively cells and also helps lower our cortisol levels which helps us relax into deep sleep easier.
AGEs not
only age cells — they bind to the walls of blood vessels, causing them to stiffen.

Those findings suggested that inadequate sleep in the elderly, who normally experience sleep disturbances, could exacerbate an already - impaired protective response to protein misfolding that happens in
aging cells.
