The oxidation theory states that free radicals — atoms with an odd number of electrons — frequently bond with cellular tissues because of their high reaction rates. This oxidation action normally damages the cell and its components over time. The real danger is when free radicals bond with DNA material, causing genetic mutation to the person or his/her offspring, which results into most types of cancers and other incurable diseases.


The first theory studies the effect of telemore shortening within a cell. Telomeres are a group of base chemicals called amino acids — adenine, guanin, cystosine, and thymine — repeated and strung together to cap the ends of chromosomes, much like the ends of shoe strings. Every cell division shortens the telomere strand, and when a pair of telomeres shorten to a critical length, the host cell dies.
