Early most mornings, I shuffle into the kitchen to make coffee for the family. You may visualise the cupboard in our kitchen above the counter to my right. This is where the family's store of vitamins is kept. There are bottles of vitamins liberally labelled from "A" to "Z". There is vitamin C and lots of Bs, and then a whole lot of minerals, such as zinc and magnesium, and even selenium. Our kitchen cupboard may hold the whole of the periodic table for all I know.
