I've set hobbies and projects aside with the intent to return to them eventually.
My grandfather gave up driving after 90. He decided he was finally old then, and passed his ancient sedan down to me. I don't think surrendering that independence was easy.
Giving up driving must be such a difficult thing as it's such a part of people's lives and, of course, once it's gone so is a lot of a person's freedom to move around at will. I'm looking forward to it, years off of course, but still far too soon.
