In scientific terms, physiological age can be understood as the relative or subjective age of an individual. In simpler terms, we can say that the physiological age is how old a person feels. Many say that all is in the mind, and if an individual has a balanced life, with a healthy diet, practice some kind of a light form of exercise continually, he/she could feel younger than the age in years.
