Dear Amy: I am 74; my wife of 53 years is 71. Our marriage is solid, and it is my strongest desire to support my wife in every way possible, especially giving her things that we may not have had resources for in our younger years. I am blessed to be very healthy, and I am an avid exerciser, now getting into short-distance triathlons. My wife was an exercise trainer, but now has injuries and aches and pains that prohibit her from joining me in my training.
