I promised Tivoli I'd look more closely next time. Here is what prevents the wanna-be steeple jacks from having a go. I also spotted one yellow triangle with a picture of lightning.

Everyone I know is telling me how fast time seems to be disappearing this year and it's just occurred to me that time speeding up as you get older means that you get older faster which means that time speeds up faster which means it's exponential. I was a bit slow on the uptake (but I'm getting faster).
