It’s funny how often I discover a cut or a bruise and have no idea where it came from. So much is going on in our bodies at every second, for the most part unnoticed. Sometimes I stop to think about it and it boggles my mind… why did my hand just ache for five minutes? Why is there a tiny red mark on my left cheek? Why does my stomach hurt? But after the pain stops, or the mark fades, I forget about it. But somewhere inside of me there are tiny cells that have been changed, perhaps forever.
