Explain Modulating Process of Ageing

Despite various researches, ageing becomes an inevitable process. The only option is to have good control measures. These are highlighted herewith:

a) Nutrition: Caloric restriction retards ageing. Isn't that interesting? This is due to decrease in O₂ consumption, decrease in free radicals and a decrease in peroxidation.

b) Exercise: Regular exercises increase O₂ uptake capacity. It improves cardiac performance and reduces muscular-skeletal disabilities. Age-related 'Resting Metabolic Rate' (RMR) gets reduced in exercising individuals and helps to increase antioxidant reactions.

The only organism, which does not die, are the unicellular ones, they just divide as two cells. During meiosis (cell division process), recombination occurs. It replaces damaged DNA. Thus, the zygote has a perfect genome. Further life continues.
