So... I was bending over to sort through some paperwork in a box and when I stood up, I was dizzy-ish, lacking depth perception, unable to reach accurately, balance was a bit off, etc.
I thought, "Ok, this it.... you're having a stroke.... glad you got the will and beneficiaries in order.... say goodbye to the world.....".
Then I realized one of the lenses in my eyeglasses fell out.
No worries..................................... yet.
