I’m old enough to remember merry-go-rounds on the playground. You could push your friends around, go slowly by yourself, or have a friend push you until the wind made your hair crazy and you felt sick. When it came time to slow it down, you would reach out your hand and let the bars lightly hit it as they flew past, walking the line between actually slowing it down and breaking your hand. They were a source of laughter but also a little scary and not the play of choice for someone like me who got dizzy easily.
