"Let's have lunch, OK?" That used to be my suggestion when I wanted to talk with someone, whether it be catching up with a friend or the need to discuss business. That was before the biometrics of Fitbit, among other things, nudged me to reach for a different way to conduct a small business meeting. Now, when I need to talk business, I often ask whether, instead of lunch, my acquaintance would like to talk while we walk in a park.
