Ah, I also have bad circulation in my hands so no grip strength and when I was a kid my fingertips were melted by a hot metal spatula that was used to BBQ further decreasing any sort of friction that may have helped (though was funny since I had no fingerprints for a while). But I love a good backpack, when I was in school I was 'the backpack kid' that rarely used their locker and now always have one when I travel.
