The spelling chrono and bio

When you say chronological aging, it is your age when you celebrate your birthday. It is also the age that you write especially when you fill out important documents, exams, or other forms. When you say biological age, it is the age or condition of your body as time goes by. For example, as you age, your organs are also aging which indicates an increase in your biological age. This is also true for other life forms abiding here on earth.
