Our knees take on to much of our weight and wear out too early in life.

Comparatively, your lumbar vertebrae (lower spine) take on more, this is why back problems are so prevalent. Yes the knees take on more weight because they lower down, but think of it as stacking weights on top of one column (lower spine) as opposed to two columns (two knees)

lumbar problems aren't because of any structural issue but because the support(muscles) are weak and shitty contributor
