DEEP DEEP DEEP subject
As most ppl do with these types of threads, I could come up with some funny jokes searching for a rep (or not cuz im not funny) but in all honesty this is truly a great question; it allows you to step away from reality and the world for a second to just ponder about all the potential things to do in this universe, what they could/should do or have done in a life and what one can achieve. It makes me realize, when to realize is to " become fully aware of (something) as a fact; understand clearly", that to realize this life we live we need to understand it. However, since our lives are so heavily influenced by others, we often forget what is important to us or make us alive. As a result, ppl often do not live the life they want and only when the idea of death registers in ones mind does someone realize if they were actually alive.
Scary thought.
I'm rambling and just procrastinating here but really it is a question that even with no answer can really make one live longer in that one day knowing you will die tomorrow than an entire life without reflecting on what your life is to you.
