How palestinian children learn about body parts

While children worldwide learn about body parts at school through a famous nursery rhyme that reads, "Head, shoulders, knees and toes," Palestinian children learn their lessons the hard way. 

As Israel keeps killing people in Palestine, children have to collect the bones of their deceased parents on a daily basis. 

When they do so, they might feel that the famous nursery rhyme for teaching body parts could benefit from a bitter twist, changing it into "Heads, shoulders, knees and bones."

Can we stop arming Israel so that Palestinian children get back to normal life?
