Maybe it’s a lifetime spent with documents in airless offices that gives partners the urge to throw themselves off cliffs or into frozen waters by way of recreation – or perhaps it’s just hanging out with corporate counsel that does it.

One City capital markets partner, for instance, is spending the week adding kite-surfing (no, The Diary has no idea either) and wind-surfing to the list of implausible sports he has mastered to international standard. The partner is such a perfectionist, however, that he has pledged to make kite-surfing the final string on his sporting bow as he simply won’t have time to master anything else before he’s past it physically. So there goes the unicycle-archery and parachute-polo then.
