Japanese cusine takes precison and care to prepare, life also takes great care. For some, eating sushi is adventurous and for others it is mundane because it's what they do every day. The same goes for life, living outside of the comfort zone is exciting to some, while taking risk is of no consequence to others it's just what they do. If you find sushi palatable and eat it often, then you must keep it well or it will spoil in begin to stink. Life must also be kept well, if you don't take care about how you live, some of the things that we choose to do can also have a stench about them. This is why if you look carefully you'll find that life and sushi have a lot in common.
