Choosing an Airlines for travel

Regarding this, try to pick an aisle seat. As much as the blue sky and fluffy clouds are appealing you will want to have the liberty of going to the bathroom or for a walk whenever you want, as well as being able to get down from the plane before the obvious old lady/fat guy/mother with children that's blocking your passage.

Completely disagree with this logic.
I prefer the window seat so you have something to lean against and sleep the whole time without people constantly passing you by.
If you don't eat or drink anything you shouldn't need the bathroom, and heaven help your sorry ass if you need to use an airline restroom anyway.
During the brief period you "can" get up you're going to be told not to anyway unless it's to use the facilities or allow someone else to, so it's not like you can really get up and stretch, plus you'll have to get up and move every time someone else needs in/out of your row.
