ELI5: How come it is easier to carry a person weighing 150 lbs opposed to carrying a tank that is 150 lb of water?

The human body is 70% water, and yet it's a lot easier to lift. Why is this?

unless the person is dead, their natural need to balance themselves will help you carry the weight, and even though we are 70% water, the only slosh effect we get is the fluid in our stomach, bladder, intestines which is minuscule compared to a hollow tank full of sloshing water that is made more difficult to carry due to imbalance.
