Hey Paul:
Another '55 baby, eh? Should we start calling you Paul, tobo (the old bad one)? As one who has passed over the half-century mark myself (2 months ago), I can assure you, there is life after 50! Party my man! It's a great milestone, certainly calls for another Alembic to memorialize the occasion, don't you think? And of course you now get the real secret revealed to you: Middle age starts at 60! (nyuk nyuk). Have an excellent birthday and on to the next 50!
Bill, tgo
