millimetres and centimetres count for what we find to count in the day to day relativities we live in..
they are not numbers, they are figures, which we figure to count and calculate no matter what type of step we do and take..
we tend to rather try figuring out the circumferences of genuine eyes, or even structures of hoped upon smiles, yet we leave out what we leave in us to be explored by us or even unresolved..
so it is a simple 1, 2, 3, to a 50mm click? i doubt it, as it is a depth beyond that..
