Of course we all expire at some point, individually and collectively. However, we almost all make efforts to push that point as far into the future as possible (the main exception being when doom is near and assured, and only increasing misery is foreseen on the way). So, why would we not try to extend the expiration date, individually and collectively? It's a big universe, so much to explore!
