Do you care whether you live or die?

I do care because my responsibility to people in this life is not yet over.  I still have a wife and children (and  grandchildren) who depend on my income and other support.  I understand the apostle Paul when he wrote to one of the churches and said that to "depart and be with the Lord" would be better for him, but he chooses to stay because his being there is better for them. His duty to them has not ended yet.

 not in a very very long time

A person can know true joy and meaning in life, and can better prepare to die and eventually meet God, if he recites the rosary every day with care and sincerity.

Us Christians are happier alive than in heaven

I am enjoying life, and I will try to stay alive as long as is reasonable.  But death doesn't bother me, and I assume it will be a new beginning of sorts.

I don't care one bit. 

Yes, I'd rather not die soon if that can be avoided.
