Every person carries their weight differently. Because people put on weight gradually, they can easily add a few pounds over time without realizing the extra strain on their body. This is due in part as to how the weight is distributed. When the weight force is divided across a larger surface area, it can make it much easier to carry. If an elephant stepped on your foot, would you rather it be wearing a running shoe or a high heeled shoe? A high-heeled shoe would be more painful when all that weight is centered on one point.
An item carried in a different manner also impacts how heavy or how light it feels overall. This is not a physics trick. It is simply gaining efficiency by using your skeleton to bear the weight rather than your muscles. To simply demonstrate, a modular brick weighs about 3.5 pounds. Hold a modular brick or other similar 3-pound item in your hand and extend your arm out fully away from your body. You will soon notice the strain in your arm muscles. Then raise your arm vertically, straight up over your shoulder. Now, that the weight is supported by the bones in your arm, there is much less effort for your muscles to hold it in that position. It’s amazing how the elements of the human body all work together in ways we don’t consciously think about often.
How a structure connects and works as a whole will also be a together be a critical factor in its role in staying strong over time. Take for instance, a full gallon of water weighs about just over 8 lbs. If you pick it up and set it down it may not seem that heavy. But hold that gallon jug of water for 5 minutes and you would start to feel tired. The design of The Dovetail Difference® is not only stronger, it will endure longer over time.
