Scientists tell us that we have a chronological age as well as a biological age. The chronological age is simply math: you were born on this day in this month in this year, therefore you are this many years old.
Our biological age is how old our body is: are you 50 years old with the body of a 30 year old? Or are you a 30 year old with the body of a 50 year old? It’s easy to understand what contributes to a difference in chronological age and biological age: it’s usually diet, exercise, and the absence or presence of other healthy habits.
I’m going to throw out a third calculator for determining how old you really are: how much of your life do you feel is still ahead of you? If you’re 20 years old, you probably feel like most of your life is still ahead of you, so you feel young. If you’re 40 years old, I don’t know. If you’re 60 years old, and you still feel like there’s still a lot of living to be done in your life–adventure, accomplishment, passion–then you’re still young.
The trick is to be Old Money, but stay young. It’s not how old you are, but how young you feel. Keep a thriving and vibrant to-do list of things still undone. The bigger the things on that list, the younger and more alive you are.
So, how much of your life is still ahead of you? The answer:
All of it.
