<human>:  What is the most efficient way to load a backpack without crushing anything inside?
<bot>: The most efficient way to load a backpack without crushing anything inside is to start by packing the heaviest items first and placing them at the bottom of the backpack. Additionally, pack items that are easily crushed towards the top and use any of the additional exterior straps to help secure them in place. Finally, fill in any extra spaces with light, compressible items to make sure that nothing shifts during transportation.
