Age does  a lot of things to us. And to our brains, which shrink when we grow older. Those incredibly complex neural networks inside our skulls not only shrink, but they also become more susceptible to scourges such as dementia and Alzheimer’s disease. People who do not suffer from these cognitive dysfunctions, also show aging effects in their brains, such as the accumulation of amyloid-beta plaques.

To trace the evolutionary roots of the aging brain, researchers have previously investigated whether similar effects occur in the brains of rhesus monkeys (which diverged from the ‘human lineage’ about 30 million years ago). These primates showed only very limited effects of age in their brains. So, the mystery remained.

Lets gamble; participating costs you only 50 cents per game. The odds are in your favor! Two out of three times, you win and get a dollar. So we start playing, and it seems as if we walk along time, every game we get to a point in the road where it splits into three paths, two of them are winning one-dollar branches, one is the zero-dollar branch, there we toss a three sided fair die, then we ‘find ourselves’ in one of the three branches. However, I cheated.

Introduction

Every time when I read an article about the phenomena, which occur far from us in the universe, I'm surprised about the attention that this Farawayistan gets compared to the phenomena in the world of the smallest. Everything that happens there is dismissed with collective names such as “quantum mechanics” and “field theory”. Rarely or never the treatise goes deeper. In this sub-nano-world spectacular images, such as appear in stories about the cosmos are not available.
