coca cola was marketed in 1970s as "brain refresher" well it contains coffeine which does infact affect it somewhat but it doesnt refresh your memory it makes you more alert
infact coca cola may be bad for memory in the long term
the long going myth about 10% brain, where 90% sleeps is a complete myth, this wuld mean people need drugs to use 100% and it just doesnt happen, this doesnt make even evolutionary sense
you need to go to a shower, be yourself and take a walk, this will keep brain and memories intact, thats all, psychologist said
