Reason for stopping: Considering the amount of research on Renaissance English barges, the time it takes to ride from London to Deptford, the time it takes to ride from Chislehurst to Deptford, what the palace at Greenwich looked like in 1595, and the current of the Thames before the retaining walls went in, that's more than I should expect.
I hate insomnia.
I'm starving, and too tired to eat. I'm exhausted, and afraid if I go to bed, I won't be able to sleep.
And I'm a spoiled brat, because I can normally sleep through a limited nuclear exchange.
