>The point is we seem to have the same interests and concerns dependent upon what stage of life we enjoy as those who came before us. Trying to change that would require changing human nature and is not within the realm of science. At least not at this moment (I hope).

Hypothetical question for you (I realize earlier I was trying to avoid specifics, but let me return to your story):

If the discovery and consumption alcohol itself changed human nature, why should there be any objection to another change in the opposite direction, but this time, more deliberate?

I am unsure why you believe that such a change is outside the realm of science. I have some ideas.
