The courage to do this
I have the courage.
The only time I wear one is in the summer under skimpy t-shirts when I go out somewhere. Then as soon as I hit the door it's the first thing to come off.

the seat belt hits all the sensitive points (lol),
it tends to frighten the horses,
it can scar children for life
and make hoodlums pull their pants up from below their asses and run.
