I have, for as long as I can remember, preferred an aisle seat on airplanes. I think I've always thought I don't want to have to crawl over people to get anywhere, including the bathroom or escaping a fiery plane crash.
But I've noticed of late that I don't actually ever get up very often, so instead people are inevitably crawling over me. So, i've been experimenting a bit with the window seat.
Turns out I should go with this new direction.
According to Ideal Bite we should all make sure to go to the bathroom while still in the airport, rather than on the plane itself. Why? Because a stunning amount of energy is used an CO2 emitted with each flush. (Toilets on the ground use gravity to their advantage, airplanes don't.)
As Johnny Carson would say: I did not know that.
