Prevailing loss of non-repeated information from genome
Somatic mutation
Radiation leads to dysfunction and death
Error catastrophe
Random errorslead to accumualtion of defective DNA
Free radicals
Ionized oxygen bind with proteins, preventing them from functioning

Repetitive DNA sequences on ends progressively shortened
