Lucy is a movie about Scarlett Johansson being the super powered femme fatale that is not constrained by living in the male-dominated Marvel universe. She gets to use all her brain and it turns out that let’s her do some pretty cool things. If I got to use all my brain I’m not so sure I’d want that power.
Apparently we only use 10% of the brain at the moment and that seems like plenty for what we need to do, any more than that and it has the potential for a lot of bad. I am able to get up in the morning and stumble around making a cup of tea on just 1% of my brain (as a Brit we have evolved tea making along with breathing and blinking) so what would I do with the rest of the neurons?
