THAT MANY?

Several times lately, I have found myself doing subtractions between two dates, such as how long I have lived in Stevens Point, or how long I have been married and being surprised at the answer.  I have found that somebody put more years into so many things. The number of years between now and one thing and another "back then" keeps growing.  I have long been an enthusiastic, impatient sort of person but I have discovered that everything in the past keeps receding!  I expected my own age to keep climbing but not EVERYTHING! I am beginning to fear I am not going to be able to keep up.  What can I do?
