Aloha, I'm surprised! Sometimes when I'm working late on my research or doin lesson plans, as a rhyming artist (like you) the inspiration just suddenly comes to me and I have to write it down. In other words, as usual, I'm looking for a distraction and I found the off-topics section of this forum Oh, a wobble cushion? Hmmm, pretty good for one's centre of balance and proprioception. In fact, they have been issued to some old ladies to reduce their falls risk - a major problem in the over 65's (obviously that excludes you, then - see no more insults ). Pretty soon you'll have an athletic poise and the centre of balance of a cat and, instead of rhyming, I'll challenge you to a tight rope walking or free-style running contest. And beat you all over again!
