She didn’t even stagger off. Heat stroke weakness will NOT disappear so someone can walk as if nothing is wrong. And ‘gulping down some liquids’ will NOT fix heat stroke. If anything, it will make you vomit and either way, you will not be able to stand or walk as if nothing were wrong.
Again, I have had heat stroke on several occasions and have been hospitalized. Mild or severe, you just cannot walk it off like she did after Germany’s national anthem was finished. No one will be ‘perfectly fine’ with heat stroke for quite some time as you are claiming she is. I appreciate your opinion but I come from personal experience. Merkel has something else quite severe going on.
I believe one turns beat red when having a heat stroke and it is a very serious medical emergency and not one where you simply gather your wits and carry on.
