When I am on a plane. Especially on foreign trips, quite a substantial amount of thoughts goes into not leaving anything behind, and thinking about scenarios what would happen if I lost or forgot something important. Of course everything of those items would be less important in a life and death situation but as my brain is already trained for holding onto my stuff I can understand why this happens. I am not saying that this is a good thing but I think ingrained habits are hard to break.
