With the factually and research proven inflammation caused by the spike protein the vaxx programs your cells to produce. Anything that causes adrenaline triggers and sudden vascular restriction / BP increase will cause the already inflamed heart to enter the territory of " FUCKED "
When I used to play Counter-Strike (1.4-1.6 source is fucked) 15 hours a day, I would get raging heart rate from 1v8+ situations. I would honestly go KD of 30/0 constantly being banned. The twitch reflexes carry to this day. I would do " No reload " runs where I would just drop my gun and grab the one from the person I killed to continue the slaughter. FPS was my first forte. You get adrenaline dumps from this very hard.
