Hi there, Parkie!
I'd say that it's nice to have another septuagenarian here, but since I can't spell it (even tho I are one;) I'll just say "Howdy, pull up a stool and make yourself at home!"
I urge you to keep up your workout regimen as much as possible; it will make a huge difference in the way you tolerate chemo; at least in my case, and my MO has come around and agrees. He had never, in over 20 years of practice, encountered a patient who would, in his words, even think of using the words "work out" and "chemo" in the same sentence.
Rather than retype my story, here's my intro which contains most of the advice I'd give anyone undergoing this particular dance. Since we have age in common, you might find it interesting (even though I am not famous for my brevity.)
