Ask HN: Have founders spoken about disabilities affecting business interactions?

I'm an imposing 6'4" and 230lbs but an arthritis-like condition has left me with a damaged right hand and wrist. Shaking hands causes mild to severe pain, and my size tends to invite joint damaging handshakes from a lot of alpha males. As a result, I resort to fist bumps and left handshakes that often take some explaining. Have any other founders faced similar problems?

Any creative handshake ideas are appreciated. High fives are hit and miss with the over 50 crowd!
