Q:
The following appeared in a trade publication for the insurance industry:

“Each generation of Americans has lived longer that the ones preceding it, as the national life expectancy has approached 80 years old in recent years. The progress of medical technology shows no sign of abating. Therefore, we can confidently predict that most children born in America in the next decade will live past the age of ninety.”

Discuss how well reasoned you find this argument. In your discussion be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.

A:
Technological advancement in Medicine is no doubt a very important aspect to be considered in life expectancy, but it cannot be the only reason for the increase in life expectancy for the entire human population. While, it is true that the medical technology has been making remarkable advancement in today's world, it is always compensated with the cost and this raises the question of afford-ability. The fact that people have lived longer than the preceding ones tells us that there is something in the people's style of living that has made them live longer. A serious research over this could have presented various ways to improve the life expectancy of an individual. Simple things like Exercising, intake of healthy food items , early to bed , early to raise are some of the good habits that will inadvertently lead to longer life.

I remember reading that, Nostradamus, the well known prophet, lost all of his family members to a flu for which there was no cure at that time. And thousands of others who died because of lake of vaccination. Medical technology now is far advanced then early age. The very fact that medicines exist in the current world for most of the illness, itself convinces an individual to take steps which he/she would have feared long time back.
