Monster of 30 years old is blinking eyes with me

I am 25 years old this year . But sometime I really have to admit that my mind is older that my age...
Everything that begins will surely end. This is an indisputable fact of living. All of us were born into our bodies some time ago, and some time ahead our bodies will surely die. In between birth and death we go through many periods, where our bodies change but imperceptibly.
That was many.. many years ago, my grandparents are already in their grave. I remember just before my grandfather died a few years back, he was a bent old man withered with age....My father had to help him to washroom and kept an eye on him so that he does not endanger himself. My grandmother died two months ago, she was senile cannot remember things. I had, on occasions leaved through the family album, inside the album, my grandparents were strong young people, my grandmother 's skin was smooth and fair. Time really changes everything. I wonder how could such a pretty young thing turn into such a helpless old people... unbelievable...I see that I am headed for old age. If I live to see my old age, I would not like to end up like my grandparents, However I do not know if this is for me to choose or not. Only time will tell.
