In descending order, which 6 things could you never do without?: Sustaining life (air, nourishment, shelter, sun and so on. . . Sex is included)

Communication with others on a more or less understandable level

An approximation of "What is reality"; also known as a basic understanding of what isn't.

An intricate language; I've been thinking lately that we should divide and sub-divide different states/ideas/feelings/thoughts/concrete and more into actual languages and teach our children to redefine their whole being instead of giving them a language that knows very little of what humans are and gives more light into how we do things.

The unknown

What would be your epitaph?: Moved with wind in his sails,

he saw oceans wider than any.

Cause of death: Cash dispenser.
