Mary Ann You seem to be forgetting about children who have diabetes, cancer, etc. People who are parents of these children would not be happy with your assessment that the unfit make way for the fit. Babies are saved (made fit) by surgery in the womb. Mother Nature is not the only force at work here. While it is true that aging brings about deterioration and that complicates PD, young people are born with cystic fibrosis, a hideous disease which took my cousin's son's life at age 35. 35 was once life expectancy. 45 was life expectancy around 1900. 18 was supposedly life expectancy in the Stone Age and Roman Empire.. This is the same mind set exhibited by people who have no knowledge of disease and think you just get old and have to die of something. Mary Ann, as nurse and CG I'm surprised at your attitude. As you must know young people get PD too.
