"Athelstan! Coffee please!"
"Sorry dear, it hasn't been invented yet..."
Coffee cures many ills, including that sleep-deprived-headachey feeling that last all day long.
But you're an Anglo-Saxon so it doesn't exist for you.
Instead you'll have to look sad and whimper:
Ic dríege mid héafodece
I suffer with a headache
[Itch dree-egg-uh mid hay-aff-od-etch-uh]
How would 'Where no man / one has gone before' sound in OE?
