Many years ago I made the decision not to sit in Exit rows as I believe that opening the door would be very hard for me to do. I am a small person, middle aged and can barely handle a 30 pound suitcase. I am perfectly willing to yield that job to a big, strong guy. Yes, I did say GUY!
I do take the precaution of counting the number of rows from my seat to the nearest exit in front of me and also to the rear. If need be I intend to get out of the airplane.
