Today, in school (summer school), my teacher made us do this experiment about girls lacking Iron... ?? She got a gold 24kt ring and slightly rubbed it on her skin, and she said that if it leaves
a green-ish mark, then your lacking iron.
we all tried it, and i was the only one who had green-ish marks everywhere, i was like danng!!
so my teacher said i was lacking alot of iron in blood or something.. so my question is,
Is lacking Iron a bad thing ? and if so what are some problems it causes and anything else that
might be going on in my system due to it ?
