Answer 1

When you do dead lifts, you shouldn’t be lifting with your back, you should be pushing into the floor with your legs with prompts you to stand straight.

So imagine the weights are stuck into the ground, you’re trying to push the earth away from you/the weights, not you pulling the weights off the floor.

Doing dead lifts by lifting with your back is the quickest way to a injury.
