Too well tuned?

Martial arts legend Bruce Lee, whom many people regarded as immortal, died at the age of only 32 of a cerebral edema, or brain swelling, after taking some sort of aspirin. I have not the faintest idea whether that pill actually had anything to do with his death but I have frequently used (or misused) this sad death as an example of how an organism could be in such a highly tuned and perfect condition that it could not resist a small external shock. 

And I used this metaphor to explain why companies nowadays, pressured by the stock market’s expectations for the next quarterly results; the latest theories in corporate finance as to how squeeze out the last drop in results; and, perhaps, even some bit of creative accounting, might be so well-tuned (no little reserve fat left) that they would not be able to withstand any minor recession. (Whenever I expose this theory, I can see in my wife’s eyes that she believes this is just my preparing an excuse for my growing—ok, grown—midline.)
