The seven causes of aging are not all equally important. Death resistant cells are more important to aging than some other causes, because these ‘undead’ cells start misbehaving in ways that accelerate the problems due to the other causes of aging. Their behaviour increases the chance of neighbouring cells becoming cancerous, the formation of extracellular protein aggregates and causes the immune system to become desensitized and less effective.
Most treatments to address these cells focus on pushing them over the edge, causing them to be cleaned up by the immune system. Some treatments are looking into modifying their behaviour to be less problematic.
