Have you ever wondered how come that you often remember things forever although you experienced them just once, sometimes even in a flash second only? (Even if you'd like to forget them quickly like the time a strange dog barked at you unexpectedly over a fence while you were passing by?)

Obviously there are some brain mechanisms at work that make learning easy and everlasting, just remember the saying "once burnt, twice shy" - then remember how often you reread stuff for your school assignments and still it "wouldn't stick"!

These brain mechanisms or neuromechanisms are today better understood than ever, what with all the new gadgets that neuroscientists have at their disposal for watching your brain at work without having to open your skull, e.g. computer tomography.

Maybe you need to train your brain for years or maybe only a select few have the brain that always remembers?
