What is real?

What can one say is actually real in life? There are so many things that appeared larger than life just a while ago, and suddenly they do not seem to exist anymore. They just fade away as though they never existed, and the world just moves on as though nothing changed. I am talking about people, events and things that the whole world seemed to revolve around not too long ago.
Muhammad Ali, remember him? What about Sugar Ray Leonard, Pele, Michael Jackson and so many other things that our lives seemed to depend upon.
These days when I see people hold on to things as though their lives depend on it, I get amused. You have it today, and tomorrow, it's gone. This tells me that one day Man United, Chelsea and Barca will all fade away too. What then in life is real? They said Coke is the real thing. But these days I'm getting used to th idea that I can live without Coke. In my university days I practically lived on Coke because I just could not get myself to take tap water; and in those days we did not have pure water.
This means that one day we may never see pure water again, or even bottled water. Things that seems so real in life, suddenly disappear and no one even puts out an obituary on them. Since absolutely nothing has enough substance for us to call real, we must build our lives on the foundation of things or someone other than the things that impress us today. Someone that has been, that is, and that will forever be. You must build your life on someone that dwells in eternity if it has to be real.
