Standards.

There are two kind of standard.

Normal people standards and Scientists standards.

Scientists standards are so damn high for normal people.

From an insight point of view, when you reach and get habit to those high standards, it's difficult to come back.

And once you there, everything seems fine: just stay in your confined Science-world.

But when you step out from this dimension and you find yourself in the real world, your standards are too much to handle for regular folks.

And that's why, in the end, we look like picky assholes.
