The truth is though, that the things that affect you the most are the things that aren't modern, the bits and pieces of human life that have been integral in human life throughout history. And I mean history, not just the recorded bits, but the 1 million years since we became Homo Sapiens, and maybe even a little before that as well.
Mortality and health, or ill health as it may be, go hand in hand and have been contributing to stress since time immemorial. We just have to look a little deeper and see the truth, the traffic jams aren't just a waste of time. All that time spent sitting in a car breathing in Carbon Monoxide fumes and generally being couch potatoey.. are bad for your health. Those schoolyard bullies are not only damaging your chances of procreation, and thus preventing the fulfillment of that biological imperative, but they're probably assaulting you for fun as well!
So it comes as no surprise to me, that finding out i'm not dying any time soon would lead to a dramatic change in my fortunes. Extra energy and a generally cheerful demeanour, probably not seen since the 9th grade, are clear indications of the physical impacts of a shift in outlook. The impact thus of the mental self upon the physical is amazing. Of course this is also borne out by numerous scientific studies on such things as the placebo effect, showing that sick people who think they are going to get better, often do.
Personally i'm just grateful for this new lease on life!
