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:

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.
