The Halting Problem

Life does not seem to provide us with any convenient way of exiting it, except by hard power-off. That is congruent with how evolution is claimed to work as, but then... why do sometimes alive beings would rather end their lives? This induces a problem, a halting problem, on these presumably-fed-up-with-Life beings.

Hehe, the Tree. In a silly data-structural analogy to "The Matrix", our real, organic system of Life and evolution could be called "The Tree". (Instead of structured and machine-like, it is organic and evolving). "The B-Tree"? "The Random Treap" would be cooler.
