Bracing Myself for...

I'm going to visit a wild old man in a nursing home next week. He likes to wander over to the women's nursing home wing, wander up and down the halls, and lie down on their beds. I don't know whether the women are there or not when he does this. I've also been warned to keep a safe distance from him as he may hold onto me and not let go. He's 101 years old but his strength isn't.
