Answer :

$\bold\purple{femur \: bone \: }$

Now question arises ...why ?

What is femur bone ?

Femur, ( thighbone) , upper bone of the leg or hind leg.

$\blue{what \: if \: the \: femur \: bone \: breaks.}$

If a femur bone breaks then u won't be able to walk , Ur legs will appear shorter than other and you will have severe pain in hips and legs . the break may injure whole function of both the legs .

your life will become hell thereafter .

the thing that has pushed our specie to date is only this bone . the 70% development has happened because our ancestors didn't broke this part of leg , or else even if a person breaks with the bone he cannot live his life further more , unless and until he don't have any specialised knowledge or talent .

and after that , what's the meaning of living such life in which u can't just do anything , u have to sit in a place forever .
