Learning new things is a wonderful habit.

There is no better way to grow than by being a lifelong learner by adding new knowledge and skills daily to our repertoire.

But…

Is there an upper limit to what we can store up there? Do things eventually get pushed out for lack of space?

“May I be excused my brain is full?” — Gary Larson’s famous cartoon.

How Much data can we hold up there?

The answer to this question is remarkable. Our brains can hold over one Petabyte, equivalent to one thousand terabytes or a quadrillion bytes.

It’s a substantial amount of data difficult to conceptualize, try to imagine 500 billion pages of text (Yeah…Maybe that doesn’t help.)

According to some studies it could hold the entire internet.

So it’s impossible to fill in our lifetime unless you are a vampire or a cyborg. You can stop worrying that old information is being pushed out by the new things you learn, as you still have space.

The problem is that the brain actively deletes data often. You can recall pretty much everything…
