Four years is a long time

I'm always sad when they're over and its not just the games. It's a metaphor for time passing and all it implies. I lost my mother since the las Olympics and I wonder what changes will take place before the next Olympics. When you're young abd even into your twenties and thirties time seems like an endless road in front of you. Eventually you become keenly; aware there's an end to it. How many more Olympics do I have? Two? Three? None?
