Genes are a funny thing aren’t they. I’ve got green eyes and olive skin, yet my sister has blue eyes and fair skin…my brothers all have ginger beards, as does my son. How we look is something we just have no say in when we are born. But what goes on inside is also something we have no say in – I’m not talking about our emotions or our feelings. I’m talking about all that gooey stuff on the inside that controls how our body works – the stuff we don’t see like blood, chromosomes and even cholesterol.
