Hula hoops became popular in the mid- to late 50's when I was 9 - 12. I got pretty good at it - good enough to win a contest at a picnic for the soldier's kids at the army base we were living in at the time (Base Gagetown, NB). I could start twirling at my waist and move it up to my neck and down to my knees without losing a beat or dropping it. Of course I was skinny as a rail and straight as a poker back then so it was pretty easy going for the hoop.
I'm glad to see that hula-hooping hasn't completely died out and that one of my offspring's offspring is following in her Grammie's footsteps.
Way to go Charlie!!
