There was an ergonomic study some time ago where if 50 # or more was frequently lifted throughout the day then there’s an increased chance of low back injury. Especially, the way they bend and twist or side-bend. They call it ‘luggage handler’s back’. So, you have all these forces and awkward postures to deal with.

Complicated to understand 🤷🏻‍♂️😅
