Since medicine seems to be your 'pet peeve'.......
In fact, medicine is not my pet peeve; on the contrary, medicine is apparently the one and only card you have to play in order to convince yourself and others that "science" provides information through investigation of the natural world which has substantially meaningful impact on the problems of humankind. This is why you are not appealing to information from any other field but medicine.
So, again, medicine is not my pet peeve; it is the only straw you have to grasp. I am most willing to set "medicine" aside to find out what else you have to offer? Let's consider "medicine" now off the proverbial table (we can come back to it if
you like) and see what else "systematic investigation via 'science'" has to offer to in a substantially meaningful alleviation of the problems of mankind.
Unless you have forebears who died from smallpox, malaria, polio, diphtheria, urinary tract infections, measles, mumps, etc, then I suppose the advances we have made in that direction would be irrelevant.
If you are of the understanding that, removing several bullets in the chamber of a gun holding 10,000 bullets is making a "significant and meaningful" change before handing the gun to a child to play Russian Roulette. I, however, would question your understanding of the words "significant" and "meaningful".
Unless, like I, you lay awake as a child, listening to your younger brother struggling to take each breath and wondering if he was going to survive the whooping cough that afflicted him, then our cure of that disease would be irrelevant.

But, I will give you that you make a nice and basic appeal to emotion with your words. Unfortunately, emotion is a foundation of, religious expression; not scientific.
Unless you are aware of the increase in life expectancy of some 15 years, just from the introduction of modern dental practices, then this advance in knowledge might be irrelevant to you.
If you are of the understanding that, extending life for 15 years in a world of problems somehow contributes to "alleviation of experience of problems"; but that would be completely backward, since all you are doing is
prolonging the experience, and not alleviating the
problems to begin with. It seems to me that you're now going off the proverbial "rails" of the discussion, since nothing about "extension of experience" has anything whatsoever to do with alleviation the problems common to mankind.
We have removed many of the "bullets" already.....and continue to remove more of them weekly.....
And more bullets keep being placed into the chamber; daily. I.e.
no meaningful change.
