Many in the tech world are looking for cures for old age. They want to live forever on earth, prolonging their life past 100 years.
Pope Benedict XVI questions this quest for "immortality" in a homily for Easter in 2010.
He then goes on to explain why living on earth for a long time is a bad idea.
Living forever on this earth would essentially prolong all the bad things about being human, such as suffering, war, violence and anxiety.
People would become even more entrenched in their viewpoints and wars would go on for centuries with the same leaders. Totalitarians would reign over their countries for generations and generations.
Instead, the solution, as Pope Benedict explains, is a "new" life.
If we want to "live forever," we need to go to the true "tree of life," Jesus Christ, who opens to us a realm of immortality that is life-giving.
Life in Heaven will be nothing like life on earth. It will be a place without tears, wars, violence or anxiety.
It is a place of everlasting peace, not simply a prolongation of our wounded earth.
