I never wore a tie voluntarily even though I was forced to wear one for photos when I was young and for official events at school. I used to wrap my tie in a newspaper and whenever the teacher checked I would quickly put it on again. I'm not used to it. Most Bolivians don't wear ties.
A teacher is never too smart to learn from his pupils. But while runners differ basic principles never change. So it's a matter of fitting your current practices to fit the event and the individual. See what's good for you might not be worth a darn for the next guy.
