Cogitation about free radicals and oxidative stress--an old concept with many new limitations.
Since its creation, the concept of OS became very popular. Manifestations of the OS were investigated, verified, proved and disproved in thousands of studies. However, the enormous amount of knowledge about OS that accumulated in the last decades had dual influence: it extended the original concept of OS considerably, often even in an undesirable way, but it also pointed to its vulnerability. The present treatise is a cogitation about some main limitations that can make the original concept of OS outdated. No matter whether outdated or only less exact, it would be better to think it over three times prior using the term OS.
