Of course age, especially old age, is nothing but a mindset. As we all know from StarTrek, we're only getting old and die because the cells in our bodies get irredeemably bored (hinting to the possibility that some cells have better tastes than the individual they're forming). And the situation isn't improved by the nocebo effect of incessant rumours about human mortality. So, don't believe anything you hear...
