I was playing an emulated version of Super Mario World 3 (SNES), and I still seem to remember how to do everything I come across...I went into each level with a key to a switch palace and got them without even thinking...I hadn't played it since I was 8 (11 years)...

Now my question is, why the hell can I remember all the scerets of a videogame I played when I was 8, yet I can't remember things I was asked to do 15 minutes ago. O_o

Oh yeah I also remember a secret on the original Donkey Kong Country (SNES) on the 1st minecart level (Mine Kart Carnage, I believe), when you jump over the barrel cannon in the begining of the level off into the oblivion, hold all the way left as you fall, then you'll be shot up by another barrel cannon, then dumped into a cart where you have to jump over just one kremling, then you win the level.

I ask once again, why?
