My brother got the death jab. He works in public service and had to choose between his job and the jab. They wouldn't have fired him, but relieved him of all duties. So, he took it.
Today he sends me a video of him putting a magnet on the spot of his death job. The magnet got stuck on the point. He put the magnet in other places and it fell off. He did it many times and it's 100% repeatable.
He got the death jab in February. He has had horrible migraines about 2 times per month since the jab.
The magnet thing is real.
Ask him to pay close attention to his environment and record everything he can when he starts to get a migraine - time, temperature, sound, light, item eaten or drunk, song or video playing, activity being engaged in, phrase spoken, electronic device time, anything that could have changed in the minutes up to the onset, find the patterns.
