This is a fantastic comic that hits home – it explains the history of the ‘argument’ you (big-brained you) are having with your subconscious every time you pass the biscuit tin.
Our instincts have served our bodies well for millennia. But they aren’t adapted to this world of plenty and abundance we’ve created. It’s only through reflection- using our conscious, determined mind- that we can rewrite our aims.
I found this comic referenced in an article by Steve Kamb of Nerd Fitness, a fantastic resource for the more geekly-minded. His philosophy is great; he has adapted the terminology and approach of video games (levelling up, for example) to fitness as a whole. Worth a look.
