Not so long ago, I heard of a female Jewish academic in the UK who practised an unusual sport, boxing, of which, sadly, she was too shy to speak in public.
But no such inhibitions from New York psychotherapist Binnie Klein, who not only took to the ring in her mid-fifties but has also written a book about it, Blows to the Head: How Boxing Changed My Mind.
According to her publicist, the experience yielded insights into her Jewish roots that would not have come "if she hadn't been drawn toward a pair of boxing gloves during a physical therapy session".
Physical therapy? I hope that is no euphemism, as in (therapist to therapee): "If you won't tell me, I am simply going to have to knock it out of you."
