Growing old and feeling old

I get tired easily these days, maybe because I'm growing old, and my body just don't function as well as it used to be.The feeling of old just doesn't make sense at all. I still can run, maybe even faster than someone 10 years younger, I had completed a couple of half and full marathons, didn't I?

But yeah, I'm getting old by the day, like the rest of the people around me. I have kept a picture of me taken years ago in my wallet, whenever I feel old, I will look at it. I may not have the looks of a handsome chap, or able to attract the attention of pretty gals, but I was once young and strong like everybody else!

Maybe I should accept that I'm growing old, but I just don't want to feel old. There are still many things I want to do. Many, many interesting things...
