Why can't the human body witstand 81 nuclear bombs?

Today, doctors found a absolutely ground-breaking discovery. Did you know that if 81 nuclear bombs next to you suddenly exploded, you would die? That's f*cking insane dude! So you're telling me, for my entire life, that 81 nukes will kill me? I've been lied to. My life isn't real.
