I am a short person. Not little people short but petit people short. Edith Ann short. I have a foot rest at work even though my chair is on the lowest setting and frankly I find this annoying. So I was interested when someone told me that I might wish to look into sitting on an exercise ball. Naturally I can only do this at home as I don’t think this would be good in the lab.
Out I went to find the right size ball and blew it up and blew it up and blew it up.
Then I sat on it. My feet were flat on the floor. Yay!
Alas there was one side effect.
Bouncing. Yes, I said it. I like to bounce and bounce. My husband thinks it is funny. I wish I had a handle on the ball to hop around the house.
Then I decided to use my new friend to sew. Umm, do you know a sew machine can bounce when you press down hard on the pedal to say, I don’t know, keep from rolling to the side? Well it does. It also causes the needle to break. I got better after 2 needles. And I did finish the pajamas I was sewing.
Now I have to limit myself between the regular furniture and the ball as the bouncing can induce motion sickness after a while.
And I’m pretty sure the ball is stalking me.

Why not get a wooden chair and just shorten the legs with a saw? Of course the ball has to be good exercise for your thigh muscles? Sitting on a ball would sure reduce the chances of falling asleep while sitting also. As for the stalking be comforted that it isn’t a pair of them doing it.
Wooden chairs are hard. the ball is soft and squishy, plus it makes me balance. I notice when I’m listening to music, I’ll start bouncing in time to the music. Not cool when sewing, but it works when I’m writing until my kids wander by and laugh at me. I’m also glad that the ball hasn’t decided to hang off the Christmas tree.
