Human thigh bones are stronger than concrete!

Then why can't we move it?

it says stronger, not heavier

that just depend on how you mean stronger, cause if your drop something from above the bone is stronger, while pearcing from the side is having a greater effect on bones than on concrete.

thats really weird especially cause im leari=nig about bones in school right now...

thats true

I've heard ladies generally lose 1% bone density a year and more after menopause so that fact is largely age dependant
