1) the idea of "devolution" is absurd, if you understand evolutionary theory. it makes a great plot device in science fiction, though.
Totally wrong. Understanding evolution should mean a better understanding of the desasterous long term effects of medical science. But we don't have to worry, that is a problem for some other distand future generation to worry about. Also medical science is hard at work developing 'super bugs' (as you mentioned) for future generations to enjoy as well.
2) nature isn't a person. nature is a category, an idea. sometimes it's put in opposition to artifice, sometimes civilization, sometimes man, and sometimes intelligence. but if you grant that human beings are animals who evolved 'naturally,' then everything we do is our natural behavior. this includes medical technology.
Nature is a rock solid mathematical force applied to all life and governed by the laws of physics in its utelisation of the recources it has available to it.
Nature is also very strongly governed by history; ie all the pieces that have been in play for long periods of time. Technology introduces many new unhistorical radical elements into nature, i mean it is almost like what happens to a body when exposed to high dodes of radiation.
In all of history, on a planitary scale, there is no greater force of distruction than technology,,, except perhaps the occasional asteroid strike!!! so i guess if technology can save Earth from another asteroid then perhaps that will make up for all we have destroyed??
but the myth is that pre-industrialized peoples have stronger immune systems because they aren't constantly curing things with drugs; westerners are taught to be hypocondriacs, which leads them to have weaker immune systems, which makes then need to be hypocondriacs. or so the myth goes.
Well it make sense that the harder you work your immune system, then the stronger it will be. People with weak immune systems probably would have died as children in the old days, so of course the general population would be stronger in that regard just by default.
Anyway, i think the key to a persons immune system is their childhood years. Similar to the importance of brain development in childhood as well. That is why babies instinctively put everything they can in their mouth,,, it is not so good for the individual baby, but a fantastic thing for the human population as a whole.
the more i learn, the harder it gets to fall asleep at night.
hehehe, i don't have that problem. My mind puts ideas and concepts 'on hold' for future reference to be dusted off and checked for relevance when a new idea comes along. It is good, im my mind, everything is connected.
