Trolling through Life (TM)
The eyesight thing is unusally lame. Looking at the route to the castle, which is in part down the London road, I don't know why he didn't say "We set off for London, intending to go home. Twenty miles into the journey I started to feel a bit odd, so we turned off the A1 and drove to the first place we could sensibly stop, which was just outside Barnard Castle. I sat there for 15 mins or so, got a bit of fresh air, but still didn't feel right, so decided the best thing was to drive back again. The next day, I gave it another go, felt a lot better so carried on to London"
