Galol,
I care for others and pary for them , but hereafter, son will not recognize his father and father will not recognize his son. Same with mother and son, husband and wife, brother and sister. Only thing we can do is to pray for others in this life. In afterhere we can do nothing for them or for ourselves.
As life in the heaven, my good Galol. Life will be so good in heaven that one would like to think of any thing relating to this world in the world after.
Second, we all be raise up in our young age. If a person dies very old he will be raised again as he was in his young age. This body, its desires of having wordly things terminates once the soul is separated. So, I am pretty sure you would come young in afterlife. My advice to you, don't be too attached with your old body
