My training partner BB's comment summed it all up: "Bollocks!"
I think she suspects I am doing this on purpose, what with lower back strain, laryngitis, pulled shoulder blade muscle...
Will find out tomorrow if it needs to be operated on . Barton fracture, in case you want to Google it.
Moral of the story: do not go ice skating with colleagues and pretend that you are still 12 years old (which was last time I tried this sport).
Never mind that I was chatting and going backwards at the time. Multi-tasking failure this time round methinks.
