Why are there only questions?

How many lives will we live? How many people will we be? How many will be loved by us and by how many will we be loved in return? When we are gone what will people remember of who we were, what we did, who we touched, how we touched them? Why do we not notice, nor contemplate while we can? When we have taken our last breath, when we have said our last goodbye, what will matter? Shouldn't that matter now?
