You know, it never occurred to me that people would be upset about age comments. Things just happen to people, and age is an easy thing to look at. Some things people should never have to deal with, but it's the (bad) luck of the draw that sticks you with it, whether it's replaced heart valves, losing a child, or being hit by a drunk driver. It stinks, but it happens and you deal with it.
In terms of VR, it never occurred to me to worry about age comments with my step son. He's 13yo, and just had his mitral and aortic valve replaced, along with his ascending aorta. You know what? He's gained 15 pounds since December. He's climbing all over the place and enjoying it (he never enjoyed climbing before), he's running. He jumps up the stairs (instead of being out of breath and having chest pains), and he's much happier because of it. His self confidence has increased dramatically!
And you know what? If he hadn't had surgery "At such a young age" (his first OHS was at 15 days), he wouldn't be here, and he wouldn't be so healthy. I am simply thrilled that he has had surgery. Perhaps a difference in perspective is what it takes. Turn around the comments to "And thank goodness that I can have surgery now instead of at age 70! I have so much to look forward to!"
