According to A. de Grey we cannot predict when humans would start to live over 200 hundred years of age. However, we can say with scientific certainty that the person who will live over 300 hundred years of age is only a few years (10 or 20 years) younger than the first 200 years old. Can you explain why?

Because of the exponential advancements in technology.

Explanation:

The reason why the person who will live to be over 300 years of age is going to be only 10-20 years younger than the person who will live to be 200 years old is because of the exponential advancement rate in technology. It will come to a point where it will only take us 10-20 years of research and development to extend the human life from 200 to 300 years.

I hope this answer helps.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
