I find myself very sensitive to bright light, or items with high levels of detail. A prime example would be at the local medical centre the other day where I was caught in limbo between staring at a patterned carpet or a glaring ceiling, but not wanting to sit for half an hour with my eyes shut. A solid night of sleep usually helps, but not always. Running in a open field is pretty much a thing of the past as there is far too much changing in my field of vision.
I'm also extremely ticklish (to the point of pain), a vulnerability my other half enjoys...
