I saw a piece about him in our regional paper, then a bit on the regional BBC news, and I must admit I thought ‘twonk’; well, not that exact word, TBH, but close. I did feel somewhat embarrassed for him. The ‘invisible ball’ thing is exactly that, I did T’ai Chi for a while, and it’s a power focus thing, a way to focus your chi, but it’s not something you actually walk around doing. T’ai chi is a martial art, just done very slowly to aid balance and focus. A kata in karate terms. When you get the focus right, you can actually ‘feel’ like a spongy, fuzzy ball between your hands. It’s really weird when it happens, but you only do it as meditation and preparation. Walking around like that you just look a prat.
