The human spine is naturally compressed due to walking in an upright position, causing more pressure on the vertebral discs and potentially leading to back pain. The horse's spine, on the other hand, absorbs shock like an elastic suspension bridge and is less likely to experience such issues. The other choices are not relevant or accurate factors in predicting back pain.
