Hormones

If you hypothesize that your hormones, which are mostly inherited, define your personality then follow this maths;

There are 50 hormones.

Say 10 discrete levels of each.

That’s 500 different hormone options.

500 Factorial is 1.2×10^124

There’s only 8 billion people, so the chances of two random people chosen from the 8 billion, having the same hormone levels is effectively zero.

Family members inherit similar hormone expression, but that’s not random.

So we are all unique, mostly.

In reality there’d be a Gaussian distribution of levels for each of the 50 hormones. But even then the numbers are such that it’s still virtually impossible to find two people with similar hormone levels.
