The biological time calendar

Time passing drives all living organismes to cellular decline with age-associated dysfuntion, diseases and death. It appeared now that ageing like any biological process is surceptible to regulation. Environmental factors such as stimuli/stresses as well as endogenous factors, i.e., expression and mutation of some particular genes might act as the main regulators. Psychological factors as a human specific dimension could contribute in delaying the senescence decline.
