The Oromo people would customarily plant a coffee tree on the graves of powerful sorcerers. They believed that the first coffee bush sprang up from the tears that the god of heaven shed over the corpse of a dead sorcerer.
Coffee in the afternoon as opposed to the morning can help you avoid that afternoon crash too, rather than contribute to it.
That's been my strategy as well. I find I have enough energy early in the day, but it's nice to get a boost in the afternoon.
What would be a good time to drink coffee then? What time do you drink it?
I like to have coffee around 13-14 o'clock, I find it gives me enough boost for the rest of the day.
