You Are Only Half Human
There are roughly 38 trillion bacterial cells in your body, meaning you are technically more bacteria than you are 'you'.
If you counted every cell in your body, you would realize you are an uninvited guest in your own skin. The average human body contains about 30 trillion human cells, but it carries roughly 38 trillion bacterial cells.
In terms of sheer numbers, you are about 56% bacteria. These microbes aren't just hitchhikers; they dictate your hunger, your mood, and how well your immune system fights off invaders.
Most of this weight—about two to five pounds—lives in your gut. If you stripped away all your human meat and bone, there would still be a hollow, ghost-like silhouette of you made entirely of shimmering bacteria.
Even more striking is the genetic gap. Humans have about 20,000 genes. The bacteria living inside you carry over 2 million unique genes.
This means that 99% of the DNA in your body doesn't actually belong to you. Your 'human' cells are essentially a walking vessel for a massive, invisible ecosystem.
Every time you wash your hands, you are merely scrubbing the surface of a biological skyscraper teeming with trillion-person cities.
