Not really my thesis, the first claim is well established and documented but the second claim is, to my knowledge, my own thesis.
I have been experiencing a slight tingling in my hands and feet (extremities) very recently. Just at the tips and it is slight but persistent. Thought it might be BP related. No health issues and in good shape. Hopefully not a sign I'll keep over soon.
I suggest googling furiously and/or webmd. Found it: you're dying.
