So, the end is coming any day now, we just don't know when. Like a pregnant woman experiencing contractions who knows the baby is coming out at any moment. Even if the contractions last 45 years after the last due date, which was 50 years past the previous due date, which was 11 years past the previous due date, with a few close calls in between and probably a few more due dates before any of this, but let's not concern ourselves with old, outdated medical records!!!
Ok then, allow me to assume that it is true that the end can come at any moment. You know what else can come at any moment?
Anything.
Any moment of any day, we can suffer a heart attack, stroke, a sink hole, a tsunami, a brain amoeba, an airplane crashing into our building, an earthquake, a meteor shower, an alergic reaction, an animal attack, a staph infection... Everyime we drive, we can get hit by a drunk driver. Everytime we fly, the engines can fail. Everytime we step outside, we can get hit by a stray bullet.
We all know that every day of living presents it's risks of dying. And yet, NONE of those reasons are ever offered for why we shouldn't go to college, have children, build up a retirement account, buy property, or work overtime to get a promotion.
Whether by death or Armageddon, all things we do in this world will be made moot. That doesn't mean we should refrain from at least TRYING to get what we want out of our lives.
