Busy Brain raises an interesting point in his comment re David Gray's lyrics, particularly the line in this post's title from Babylon. [Hey BB - the song is about modern Babylon!!]. Admittedly, the thoughts conjured by "chemicals rushing through my bloodstream" are disconcerting. However, I have to think about Gray's reference versus the general status of chemicals in the blood stream. Of course all of us depend on the natural chemicals in our bloodstream that sustain life, so we will not dwell on that. What I am thinking of is myriad chemicals that many US folks put into themselves on a regular basis, and I will start with me:
Generic naproxin for minor knee and elbow pain;
Generic aspirin which supposedly helps the circulatory system and other biological processes;
Caffeine that helps the wake up call and may have other beneficial effects;
Ethanol that in moderation is supposedly good for you!
Now - what about other things that folks have rushing through their bloodstreams?
Too much sugar - just look at the epidemics of obesity and diabetes rampant in the US;
Too much alcohol - destroys the liver and kills innocent people;
Nicotine and dozens of other chemicals, most of which have serious adverse biological effects;
Viagra and other such chemicals - nearly 100% needless;
Lipotor and related chemicals - making drug companies rich without having much effect on health;
THC, meth, cocaine and countless other illegal drugs with serious negative effects;
Countless drugs intended to relieve the signs and symptoms of decades of bad habits.
And the list goes on - I think you get the picture.
