I believe human will increase lifespan by medicine, and in fact we know it works well now，but every medicine has its side effect ，so take this point，I trust genetics would be a better choice. also. maybe or machine can help people to live longer, but as human， if we change our brain or heart someday，can we feel love or hate still？

Hi, hamidreza.

You seemed to be very excited by the fact or dream that we have leading edge of knowledge and technology now or in the near future. No, I doubt. Life span is genetically determined within the control of the body. And environmental factors may delay the wear and tear of the cells in the body. Nutrition and physical exercises will increase a good quality of longevity, but not a poor quality of longevity. Mechanization cannot be a great help to delay cell death or senescence in the cells in body.

Just compare life expectancy before and after the discovery of vaccines and antibiotics.
