If someone is healthy , it means the person is not ill. If the individual dies at a mature - not old - age of 120 years from no illness, but he or she dies because the individual is term limited by God , that person dies healthily . New Scientific Data Suggest Faith in God Can Prolong Life. Researchers at Pew Research Center Religion and Public Life Project (2013) conclude Americans will live to be 120 years by 2050. Some other studies suggest the first babies to live to be 150 are already born . Taking the Bible at its word, and accepting Genesis 6:3 as it is, some Christians believe God decreed human life to be term limited to 120 years, while others argue Moses notes in Psalm 90:10 sin reduced human lifespan to "three score and ten." But he died. "He was one hundred and twenty when he died, yet his eyes were not weak nor his strength gone." (Deuteronomy 34:7 )He died healthily. What would you do if you had scientifically proven formula for living disease free to be 120 years of age?
