They say your cells are completely replaced after 7 years. Skin cells live a few days. Blood cells can live up to a year. Some cells are constantly dying and being replaced. But the cells in your mind will not die until you do. So in 7 years, maybe your touch has been erased from my skin, your chemicals leached from my hair, and your taste will have been stripped from my tongue. But in 7 years, the marks you left in my mind will still be ever so present.
