Death Age

i don;t know at what age i will die. i don;t know how many years i will live on this earth. i can live on this earth ,till god permits me. mostly i want to live on earth for 100 years.but my health will not permit me upto that time i think.now i am 35 and want to live for 25years more.till my grand daughters marriage. hope i will live upto that time. my desire is to live upto 65 years and don;t want to depend on others in my old age.now a days all are throwing the old people in old age homes. and i don't want to live in old age home at that age.

I would like to die when my son is settled in his life and when I am no longer able to be independent. I don't want to be dependent on others.
