I had west nile a while back, I guess I wasn't so lucky and I had the sweats, the pukes, and paralysis for a week and a bit. Having to ask someone to hold a bucket closer to your head right before you hurl is not easy at all, I missed more than once...
I've also taken a large bolt to the face right above my eye, a little higher I would have been brain dead, a little lower I would have lost my eye.
