I reckon you can't waste a life. Every life adds a little bit to the rich tapestry of life. The great thing about the earth is the massive diversity of the lives that take place on it. To make a tapestry, you need a huge number of stitches. If the stitches were all identical, it’d be terribly boring. Each stitch interweaves with other stitches; this is what holds the tapestry together. Equally, the tapestry has to have an edge, where some stitches will interweave with less stitches. The stronger the bonds are between the stitches, the stronger the tapestry, right?
