How old would you be if you didn't know how old you are?

I probably read this question somewhere on the internet some time back and it hasn't left me ever since. I have an uncanny urge to ask this question outright to everyone I know, both young and old. Not that I am a purveyor of moral values or even consider myself to be one, it's probably an inexorable curiosity which seems to be reaching out for the past. Or maybe it's because I can probably guess at what the answers are going to be, so my cognition is abetted by my curiosity. I know grief when I see it; I feel it myself too, it deftly amalgamates into my subconscious, while happiness and love ooze out and rarely need explanation; grief always does.

And I know, every time I ask this question to you, you'd go back to that exact moment where you could've gathered a little more courage to dignify what you had back then, to have it now in all its glory. Mistakes. Regrets. You're always under the haunting shadow of them all. And you'd give anything to get rid of the reminder of it all which is your age. Rewind, pause, rectify and replay or perish. If only it didn't slip away. If only you were...Edward Cullen? Forever young. The mere thought of it is exhilarating, isn't it? But then your life would always be at stake (pun intended). 

We don't realize it often that what's passed is past. Moments come and go; all you can do is reflect upon them and keep on moving forward. And perhaps age is nothing but a number and all you ever do is stop, rewind and reflect. That's how I've always felt about it, age is a disconnection from all that I could be or could've been; a jagged edge to my otherwise unruffled exterior which cuts bits and pieces of me every time I go back. And then I have to hide the bleeding, hide the pain. It's self-annihilation at its best. But some people have the remarkable resilience to embrace age with grace, some whose point of view is anything but awry. 

So I probably can't answer this question astutely. I know I am a child if I claim to know everything but know nothing at all. I know I am mature if I am wise and have a high emotional intelligence to make life-changing decisions. And that's how I can be as old and as young as I want to be.

But still, tell me, I’m intrigued- How old would you be? Would you go back to being 5 and experience watching the rainbow for the first time? Because that’d be breathtaking.
