Well, that statement is a reduction, and it sits solely on the negative side of life (or maybe it's saying things not mattering is a good thing, I don't know). Life is many things, though yeah, it's true that it's a dark world. But, as some things get worse as we age (such as our declining looks and health), other things get better. 1. we get wiser, and 2. I think what happens is we become more and more "ourselves."
