Java jive

Yesterday was International Coffee Day, it seems.  Did you know that the optimal time for having your first cuppa is 10 a.m?  That's a bit late for me, and I would imagine, most of you.  I have a coffee machine by my bed and have my first cup watching the news around 7.30.  It's all to do with a hormone called cortisol apparently which gives you that "get up and go" feeling first thing in the morning (can't say I've ever experienced it myself) so you should wait until your cortisol level subsides before having your first cup of Joe - around 10 o' clock.  Well - each to his own.
