Instead of a fan, couldn't you just have a motorized bed that would spin them rapidly around the room?

I'm not sure if that'd be conducive to sleep though. lol

My Dad got chickenpox twice.
Everyone was so convinced it couldn't be chickenpox that he was allowed to be around my Aunty (his sister in law) who was pregnant.

She subsequently caught it and it caused a lot of anxiety about whether my cousin would be affected (he wasn't)

My old neighbor back in Cherry Point had a daughter, who died of "SIDS" at about four months. They demanded an autopsy and every test invented by mankind on the child, wanting to know what REALLY killed her. Turned out, it was a deformity in her brain that her pediatrician never caught.
