Well, MOST of the older people prefer aisles.
I certainly don't consider you old Vulcan. I feel OLD (I was born OLD) but really we are "ageless" (It's how you feel.)
JonToner just reminded me of two other reasons for my 1B aisle seat:
*Closer to the exit (unless i"m in a 757 or 777)
*Closer to the rest room (as soon as the seat belt sign is off, I dash.)
