the song remains the same

so i was listening to an extended chat by a noted american neurologist a few weeks back. during a pa session at my school. and for the better half of the afternoon, the good doctor was busy expounding upon the neurological differences between the typical adolescent brain and that of my peers - that is to say, that of the older generation. and while many novel and compelling factoids were dispensed with over the course of the afternoon, i must say that the lone tidbit of information that stood out from the rest that day was the one pertaining to the degenerative human brain. or more precisely, my own degenerative, simian-like brain. because according to the good doctor, the analytical component of the higher order cerebrum begins to gradually decompose around the age of 32. but somewhat fortuitously for the thirtysomething crowd, several alternate components of the homosapien encephalon appear ready, willing and able to compensate for this creeping breakdown of rational function so as to stave off hyper-senility until well into one's forties. but that, according to the good doctor, is where the miracle of nature inevitably begins to loosen its grip. for around the age of 42 or 43, the progressive rot and decay of grey matter north of one's hairline can no longer be denied... or ignored. and that, my friend, is where it all begins to make sense. for i cannot remember the last time i... i... i... well, i just can't remember.
