Is it true that some day the common lifetime of a man can expand?
Answer 1:

Sort of.As humans age, their bodies deteriorate. This makes them more vulnerable to diseases and other problems. As medicine improves, these diseases and other problems can be lessened, increasing the life span. However, this does not change the fact that at some point, the body will get weak enough that it can't live even without diseases. This age varies from person to person, but it is probably between 80 and 110 for most people, and short of genetic engineering turning people into something else, I don't see this ever changing very much. However, many people die in their seventies and earlier, and for them the span of life can be increased.
