In wrestling, speed counts. In travel, faster means you can get there and begin having fun sooner.
I still feel that way much of the time. I really liked "Faster" by James Gleick. But, I am finding that there are pleasures in things that are slow, too.
I was bothered by diverticulitis for about 30 years and I am confident that wolfing food and not chewing it well did not help.
I read that the international organization Slow Food was explicitly started to work in the opposite direction from American, and increasingly worldwide, fast food.
I found that having a sore back can sometimes be alleviated by slowing rocking on my back on the floor in a knees-to-chin curled-up position. With that problem and some other muscle troubles, moving through the range of motion that is painful at normal speed can be helped, sometimes fixed, by a glacially slow but smooth movement through the action in question.
