I don't think this is exclusive to deadlifts either, the main physical benefit from weightlifting (strength training in particular) is that you can lift heavier things. Yay!?
Any outdoorsy activity is vastly superior to it due to exposure to fresh air and sunlight. It also tends to be less boring and monotonous than lifting heavy things for some inexplicable reason.
