Time

The moon has been hanging around the Earth for 4.5 billion years. Ive been hanging around the Earth for 58 years. I feel old some days.And when I think how long the planets have circled the sun,I still feel old.
We have no true concept of time.We have no idea what 4.5 billion years is. All we know is it is a long time.But then 58 years feels like a long time.
I think about time a lot as I get older. I feel sometimes like our life is like a spinning top. When we are young our lives are centered in the middle of the top,where the circumference is it's widest,therefore each spin at that point is at it's longest width.and as we get older we move closer to the top where the circumference is smaller and the length of the rotation is shorter. So even though our days are still 24 hours long,the days seem shorter the older we get.
I had a golden retriever once who passed away at the age of 12. I remember thinking how short a life span that was. But my dog lived a full life. He had no expectations. He just got up every morning feeling like he was going to live forever. But when he got sick I felt for the first time he knew his life was going to end soon.I could see it in his eyes. He could hardly walk towards the end,but the night before he died he somehow managed to find his way to my bed and he lay next to me the entire night.He had never slept there before. It was if he knew he was leaving me,and he wanted to spend one last night as close as he could to me.
Those are the nights I wish time stood still.
