and have spent decades trying but failing to convince anyone of their incredible significant. I appreciate your recognition as it gives me some solace that my campaign wasn't in vain.

.......having a stroke five years ago. No need for sympathy as all my other symptoms resolved completely. I can't curl my tongue but every member of my family seems to do so quite easily. I can cross my eyes easily and can also move each eye inward separately for a sort of "half-crossed" look. Thanks for the opportunity to tell the world about these skills.

I put might right index finger on my tongue
Then I put my left index finger on my nose at the same time
