10 years ago, I found out that my Dad had had a heartattack and was in bad shape. I lived 7 hours away and started driving at 7pm. When I got to the hospital I was told that they flew him to a larger hospital 3 hours further away. After 2 more hours of driving, I started hallucinating and could not keep myself awake, so I pulled off the road for a power nap. It only took me a few minutes to recharge and get back driving. When I finally got to the hospital, I was informed that he had died during the few minutes that I had stopped to rest. In my mind, my Dad realized I was endangering myself and convinced me to pull over.
