Age is whatever you think it is. You are as old as you think you are.

Age isn't how old you are but how old you feel.

Age is nothing but a number. It is how one ‘rocks’ one’s age that matters.

I used to think that eighty was a very old age. Now I am ninety. I do not think this any more. As long as you are able to admire and to love, you are young.

Age is just reality we create for ourselves.

Age is not measured by years. Nature does not equally distribute energy. Some people are born old and tired while others are going strong at seventy.

Why were you so old when we met? I answered with the truth: Age isn't how old you are but how old you feel.

Someone has said, "It is not how old you are but how you are old." The way I was old today on my eightieth birthday is that I have just entered the infancy of middle age.

You are as old as the risks you take. In many ways, aging is not the process of growing old, but rather the slow death of becoming overly protective, scared, and worried about losing what you have. Youth is found in the energy of going for it, taking the risk, and trusting that you'll figure it out along the way.

Your biological age is the number of days you've lived.

Your psychological age is the number of thoughts you've entertained.

Your sociological age is the number of contributions you've made.

I think age is terribly overrated. You're okay as long as you don't grow up. By all means grow old, but don't mature. Remain childlike, retain wonder, the ability to be flabbergasted by something.

Age is not a particularly interesting subject. Anyone can get old. All you have to do is live long enough.

Age shouldn't affect you. It's just like the size of your shoes - they don't determine how you live your life! You're either marvellous or you're boring, regardless of your age.

I do not think much of ages. People are people. What does it matter how old or young they are? It is a category, and I do not like categories. It is a sort of pigeonhole or a label.
