Been there, done that. I am a retired rocket scientist.
My brains synapses are firing at warp speed while yours are still at the speed of a Cro-Magnon or Neandrathal.
You're still processing Sesame Streets "COOKIE MONSTER SINGS C IS FOR COOKIE" lesson while my superior brain is working out quantum theory, quantum physics, the theory of relativity and how wave-particle duality, superposition, nonlocality, and decoherence all play ther part in this thing we call "life" and "death".
