@laverne Hi Laverne, It sounds like about the same diagnosis at about the same time of my life. Actually, I I was diagnosed a couple of years earlier than you and I am now almost 74. And I felt panicky and horrified that this has happened to my body. I worry about it only enough to keep me from doing something dumb like lifting heavy items, pushing something or dragging something heavier than 25 lbs. Actually, for pushing and dragging, I assure the weight is much less than 25 lbs as there is always the inertia which adds to the physical stress.
I go to the gym every day, spend 35 minutes on the strider, do another 30 minutes of core exercises but I am careful with weight training. I work slowly with lower weights. So far, so good, aneurysm is stable. I have never had any pain and my diagnosis was also "incidental".
