Cease to exist for the sake of living

There is no logical excuse one can come up with to justify not living... Especially with good health. Given, people with two working lungs, a working heart, normal internal and external body function may exist... The real question is however, are they living? Life is a choice. Choose to live it the way you may please, if you even please to live it at all. Why not go out and explore the world? Why not cliff dive 100ft+ cliffs in Hawaii? Why not sky dive from the top of Burj Khalifa? Why NOT? If you can ask "why" to every opportunity given, I would like to know "why NOT?" I mean after all, you can live or exist but you can't really do both at the same time...
