His reasoning is based on the body tissue that results in metabolism. He said the effects of metabolism are what brings about growing old in human beings. He felt the need to enable people not to lose the ones they love anymore due to health issues, lack of liveliness, and the ability of functioning in ageing process (De Grey, 210). He felt this loss had to stop since the majority of the people that died due to old age always had agonizing and very expensive death. The expense was due to that old people were vulnerable to lots of diseases and there most of the time is spent with medical assistance. Old people are not productive. This is because they can hardly assist in any job. They are therefore seen as valueless in the society.
