Certainty is just an illusion, your life can be filled with unpredictable moments and wonders, or it can be filled with monotonous routines every day. Each day, you may die or each day may become your last day, just like everyone else.
If I think about it, a lot more people die in the comfort of their own homes, near their homes or at their workplace rather than anywhere else. Just because you are comfortable, does not mean you are safe.
