When I was a young-ish person, I was always warned that if i ever dared to eat the black seed within an apple, that one day I would have an apple tree growing inside my insides. The same applied to swallowing the cream seed that you find in an orange.

I believed that for quite some time, maybe even for a few years, until i realised that regardless of how many seeds i deliberately ate to test this theory or accidently ate, it was never ever going to grow inside me, because the conditions inside my body were different to the conditions outside my body.
