Blimey, I leave this thread for a couple of hours, and it's all about actuaries again. (TA = The Actuaries, an everyday tale of insurance folk.)
Songbird - wow! Good find; I'm pretty sure that's it: guy was reading brochures about health products and got off in Watford where DDD are based. All very strange.
helena - a large proportion of the male actuaries have receding or grey hair. I have neither, so your DH is making sweeping generalisations. Does he work in pricing? (Reserving actuary's joke). Oh, this is so tantalising: give me a clue - eg does he work for one of the consultancies or what are his initials?
