This IS a good appendix to this thread!
Many thanks, 38976!
Great info to have in one's hip pocket, just in case.
It might even work on oneself.
Sharon Stone wandered around in her home for eleven days, unable to help herself or to call for help, before someone found her.
Apparently she had called someone, at the beginning, and said she thought she was having a stroke. But, she wasn't believed. Then she lost awareness of herself and what she was doing.
She advises, if you get the worst headache you have ever had in your life...get help immediately!
Maybe we could do the STR and stick out our tongue, while we wait for help to arrive.
A good note to put on the fridge, I think.
Thanks again.
