Time flies
Passing 60es and to be over 70 years old, it will be harder just to enter another year. As you are this old, your inner power and your body structure won't to be able to take much load as you have accepted in our 40es or 50es.
One year of 70 years old may worth more than a few years of 50es. Unless you take good care of yourself, it won't to be easy to receive any extra load to your body or will power. It means that one year would worth much more than a year of your younger age. As your remaining years become shorter yet your days pass this fast, you must take care of your remaining days.
As being a child of your beloved parents, if you leave them somewhere else and do not take care of them, you must call yourself a fool for losing the last chance to show your appreciation of being born on this beautiful earth.
When was the last time you talked with your parents? Well, I lost my parents during my thirties when I was busy with daily affairs. So, I didn't have chance to talk with them and to show them my appreciation.
Don't I regret? No, matter of fact. For me, parents are some remote existence detached from my daily occurrence. But as I get older and since I have reached 60, I feel like conversing with them every once in a while. Nothing special. Just to ask them what I was like. Was I a wheedling child? Was I good at riding tricycle? Was I good to the grand ma? Oh ,well I feel tears come out. . . .
