Age is just a number.

I’m coming up on a birthday soon. It’s hard to not connect birthdays to aging once you reach the mid-forties. 46. Is that really how old I am?

Let’s take a closer look.

The youngest atom in the body is more than a billion years old. Hydrogen, the most abundantly found element, is nearly 14 billion years old and was produced during the Big Bang. Carbon and oxygen atoms are between 7 and 10 billion years old. In other words, we are really really ancient. What’s another 20 or 46 or 72 years in this cosmic scheme of things?

So how old did you say I was?

Cells in our body die every second and new ones replace them. In a sense, we are re-created with each passing moment. A liver refreshes itself in 3 months. Taste buds in 2 weeks. The lung’s surface in 3 weeks. The heart refreshes 2-3 times over a lifetime. Cells in the intestine in 2 days. In fact, only our eyes are as old are we are, not undergoing transformation over time.

So we are made of ancient cosmic dust but renew ourselves in some cases as often as every 2 days and sometimes never?

So, tell me again. How old did you say I was?

Each of us, like a chicken, started off as an egg. From the egg that came from our mothers, that is. The thing about a human egg is that it is formed when the mother herself is an embryo. And we could argue that the formation of the egg, half of which contributed to each of us, is technically our first moment of existence. So, if your mother had you at 25 years of age, and you are 30 years old, technically you are ( 30 + 25 = ) 55 years old.

46 years. 2 days. 14 billion years. Add your mom’s age to yours. Take your pick.  I told you that age is just a number.

And happy birthday to you too (for whenever the day comes). Remember that you are this newborn baby that has existed since the beginning of time and will last till the end of it. Many happy returns of infinity to you.

Imagine the consequences of being alive for 200 years. Would a longer life be a curse or a boon? Interesting questions.

Life in uncertain. Why do we struggle to comprehend uncertainty? What can we do about it?
