Real measurable differences in brain chemistry between people describing themselves as larks or owls.
Is that actually true?
For as long as I can remember, I’ve never been a morning person. As a kid I could never get up for school, and as an adult it’s still a real struggle of a morning.
I’ve tried going to bed at 8pm, going to bed at 4am, and everything inbetween. I’ve tried eating before turning in, drinking, abstaining, nothing makes any difference.
I always thought it was just me being crap.
