Life expectancy in 
								
								the US
								
								
								                        
								
								
								
								Life expectancy is generally 82 years in 
								developed countries (US 
								- 
								
								France - Canada).
								
								
								 
								
								
								Consequently, most men and women aged 60 in 2022 
								will be dead in 20 years
								if no prevention is applied.
								
								
								The significant causes of mortality after 60 
								years are:
								
								
								1. Diseases of aging that develop during the 
								last twenty years of life in the absence of 
								prevention
								
								
								2. Cancer can develop in any organ.

								Recent advances in
								cancer research are already significant. For 
								example,
								genomics makes it possible to study tumor 
								cells and use precision medicine.
								
								
								However, this precision medicine that eliminates 
								cancer cells
								will have to consider the prevention of diseases 
								of the aging body as a whole. Otherwise, 
								there will be no more cancer patients but a 
								degenerated population 
								
								with Alzheimer's disease, and 
								
								waiting to die.
