My dentist is a wonderful public speaking coach.
He was the one who first showed me, decades ago, how helpful being aware of your body is.
Here, he said, and touched the tip of my nose, then, and today. Just breathe here.
And I did. He also showed me how important it is to know how long the suffering will last.
There is a fine line between saying: I will talk for ten minutes and I will talk until the spin top falls over and stops/the sun goes down/I run out of ideas.
Eternity is hell and no exit signs.
But if I tell you there is light at the end of a tunnel of 85 dense slides, you may survive even that. Just keep breathing.
