Often the first few things we need to use in the morning – toothpaste, hairbrush, medication – are the last few things that we used the night before. So logically they should be right at the top of your bag. Instead, every single night whilst you are sleeping, these items will mysteriously work their way down to the very bottom of your bag. Regularly I find myself in a brand new city, desperate to get out and explore, only to be delayed for at least twenty minutes because once again I CAN’T FIND MY TOOTHBRUSH!!
