I'm on JetBlue and United. So I spend a lot of time on airplanes with other people and in terminals or just traveling around and going to restaurants or whatever. The interaction I get on a daily basis is always positive. I've never had a negative interaction.
Obviously, I come from one background, and the people that design fitness equipment have been doing it for years and years, and they know what works and doesn't work.
Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something else will take its place. If I quit, however, it lasts forever.
