train travel
"Train travel is like spending time in an airport lounge (though the feeling is not the same now, with too many channels of communication available). You are, to a certain extent cut-off from the world and suspended in a space where the focus is more on the moment than what is ahead or was behind."
"Train travel is like time travel - the hours slip by with the miles, leaving us with nothing but our thoughts."
"Train travel is like meditation. I can spend hours daydreaming during my journey; I read, stare out of the windows or into nothingness and finally fall asleep to the somewhat reassuring clacking of the wheels."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
