I'm not old

So the opening scene from Holy Grail keeps playing in my head where Arthur accosts a peasant who turns out to be neither old nor a woman. Dennis the peasant claimed to be 37 which today I am as well. As I reflect on my age I am struck by the realization that in three short years I'll be 40. That is a big number. I don't feel particularly old although I do realize that there are things I just can't do anymore. All-nighters have more severe consequinces, I can't eat the legendary amounts of food that I used to, I have to wear glasses more and my teenage sense of invincibility is long gone with my hair. I think of the promise of tomorrow that was portrayed in my youth and how it compares to the reality and have to laugh at all the differences. We still don't have flying cars and still depend on fossil fuels for energy but who saw texting or facebook or iPhones. I have a 12 year old son who has never known a computer without a GUI interface or life before the Internet was accessed with modems. My youngest daughter assumes that handheld devices have touch screens. Makes you wonder what wonders they will see develop that we have no concept of now.
