Nice, Joanne. It truly is often a "spend it now (on good food, good learning) or spend it later (on chronic disease and its attendant 'sick care')."
p.s. I'll save you a bit more, if you haven't already figured this piece out: if you had positive titers a couple of years ago, no need to continue to track them. They will fall over time, Nature conserving energy as she is wont to do, but that in no way means immunity is lessened. Here's a page with more on that, for anyone that's trooping in for yearly titers.
