How you feel about yourself, carry yourself, and present yourself dramatically impacts the way you relate to your environment and other people in it, which in turn dramatically impacts your quality of life and how you age.

chronological age, which is the number dictated by your birth certificate.

biological (or physiological) age, which is how old your body “seems” based on how well you move, look, and function.

emotional age, which is how well you manage your feelings.

social age, which is based on the expectations society imposes on us about when life’s major moments should occur (such as graduating from high school, starting a family, or retiring), and about what appropriate or inappropriate behavior should be for someone of a particular age.

psychological age, better known as “how old do you feel?” It’s the age that’s entirely up to you because it’s however you see and carry yourself.
