The latest medical advancement is not able to extend the lifespan of human individuals very much. Nanorobotics for wound treatment inside the body are not invented yet and even simple questions like “which food is the most healthy one” isn’t answered by university research right now. For most diseases no effective treatment is known, that means that each year many people die simple because they are too old and fall ill into a major disease.
The good news is, that it is possible to predict how long new born humans have to life. According to https://www.death-clock.org/ a male student who was born in year 2000 in the US will die in the year 2075, that means after 75 years in total. If he makes a bit sport and stay’s healthy he can reach one year more and will die in 2076. That is given by so called mortality tables which is the basis of a life expectancy calculator. In the sum, these predictions are working surprisingly accurate, that means the individual can plan what he want’s to do with the years he has.
There is another good news: in the last 50 years the life expectancy has increased dramatically. A few decades ago an average person died in the age of 50-60 years, that was for today’s perspective very young. The sad news is, that even with modern medicine it is impossible to raise the lifespan to 100 years and more. Even if somebody selects every parameter in the life-expectancy calculator to the optimal value, which means not drinking any alcohol, making sport everyday and be happy with friends, he is not able to life very long. The problem is, that aging is a biological process which has to with with cell modification inside the human brain. That means, under the condition that the environment provides the best conditions for staying healthy, the human body will become ill after some decades. The most obvious sign are face fold but the cells themself get broken too.
In science fiction movies a possible bypass to the problem is explained. It is called Nanotechnology and means to use tiny robots which are injected into the blood stream for repairing all problems from the inside. In theory, nanorobots are able to cure any disease, but today’s medical research is far behind a working prototype. That means, such technology isn’t available right now and it will take many decades to develop such robots.
