Yes. Let's say you have a 6 foot tall man who weighs 175 pounds. You don't just scale up. Using the square cube law (which states that surface area is squared and volume is cubed), if the same man was made 12 feet tall, the femur would need to be EIGHT TIMES normal thickness to support the weight or it would snap like a toothpick.

Elephant, indeed.

1984 was a warning, not a how-to guide.
