That dancer's trick for boating

My dance technique to avoid seasickness, recorded on this blog back in 2007, worked again.
This time I was able to teach it to a visitor from the City (NYC).
While I was out sorting my mother's stuff (rainy weather, not too hot- I made a dent in the attic) the visitors went out on Joe's motor boat, and one came back woozy.
We went again yesterday, and she stood next to me, not sitting in the choppy seas, working with the knees to keep ears level. My mother's old suggestion, "Watch the horizon," is a start because it makes sure you don't look down or up, but knees as shock absorbers are the crucial extra step. Can be tiring, but better than feeling sick.
