What i think this stupid person meant is: lead is poisonous because lead replaces the other bits of metal in the molecules of the air, dirt, gasoline, and our own body. The molecules won't function right and can cause the body's' major organs to shut down. Those organs are your heart, brain, lungs, and kidneys. Lead can be found in gasoline, toys and other products made before 1976, paint made before 1978, toys and other products made outside of the country, bullets and many other things. Pencil lead isn't poisonous because it isn't actually made of lead. You can touch lead without risking your life but breathing in lead dust or swallowing lead will cause health problems or death.
