Actually this is a very dangerous sign. My grandpa did the same for his last couple of days, before he tripped and fell down the stairs, where he was violently murdered with a chainsaw.
Reminds me of my uncle. He'd been acting weird, getting nervous whenever we talked about his new roommate. Couple weeks after he started acting weird, he tripped and fell in the shower. Landed right on the shampoo bottle, had to go to the hospital and get it removed
I still wonder about that. Remember seeing it in that TV show... Quarry, was it? and thinking, "well, another American food abomination. Why would you add butter to coffee?"
Never did give it a try. Seems so weird.
