RE: Does Aging Make Us "More Ourselves?"

I am 68 years old, and find myself being more blunt than I used to be. I have an older sister who has never had a filter, is quite self-centered, and has a reputation for being outspoken to the point of rudeness. I don't want to get that blunt. But I do want to be more comfortable expressing my true opinions and beliefs, if I can do it without coming across as a cranky old lady.
