Then there is your bodies imperfect self cloning process. Yep, self cloning that like any copy gets fainter and fainter the more copies that are made. The last numbers I heard on self cloning was a complete self replacement every 7 years with loss of gene information along the way which means we all loose some of ourselves in the process.
My understanding is that your neural tissue does not undergo replacement. Once you kill off a few brain cells, they don't grow back or anything.
On one hand, I'm not pleased with this aging crap, but on the other hand it could be much much worse. I see people younger than I in the obits all the time.
