One Of Those Moments

Occasionally we all have one of those moments where you go "what day is it?" Theresa has about fifty of these everyday hilariously. But seriously, what time is it? Okay, I actually know what the time is but I don't think my body does because it's nearly 2am and I am wide awake. It's something to do with having so much time off work because of Christmas and New Year, but I would pay good money [Monopoply money] to the person [scientist dude] who could coherently explain to me exactly why this happens. So there is your challenge for the year, your goal is to find out why my body doesn't know what day/time it is. Go!
