Do you ever get worried about living alone?

Sometimes, when I get out of my shower, I wonder what would happen if I tripped on the edge and banged my head on the wall and knocked myself out. How long would it be before someone found me?

This brings up all kinds of vague worries that I imagine couples or people who live with others might not have. Unless they do. What if you normally live with others, but they are away for a while. Do you have extra worries about yourself? What would happen if you got sick and couldn’t get out? What if you had an accident and were bleeding severely?

Do you have such worries? What are they? Have you ever had an experience where being alone was a real problem? What was it?
