Why does life fly by when you get older?

Me and Heather around 1980.

I have always been extremely sentimental...I think to my detriment. I miss being a child in many ways. Mostly because my parents were so young and fun, and me getting older means that they are also getting older.They were so good to us. We didn't have much money, but we had everything we needed and more. Life was good. I have always been family oriented. When I went off to college I wrote my parents a letter and told them how much I appreciated then and how much I had loved being in our family. We all cried together. I left for college when I was 17 so the better part of the last 17 years I have been away from my family for long periods of time. I have lived a lot of places, and loved traveling around, but I was never 100% happy because I was away from family. The last almost 2 years I have gotten to live close to my family, and it has been wonderful. I worry about the day when I will not have them anymore. I know that may sound morbid, but I have thought about these kinds of things ever since I was very young. I guess the moral of this post is that I need to show them how much I love them and appreciate them so that they know. Working in a nursing home is very rewarding, but it does constantly remind me of the brevity of life and the importance of saying I love you.
