We have to admit that most of our thoughts aren't even our own.
"No", you say, "I think what I want to think, I think my own thoughts."
Are old people beautiful? If that seems obvious to you and you say that they are not, then I say you were likely programmed when you were a child about your standards of beauty.
When I was a child I was amazed at wrinkled skin that felt like tissue paper, like it could rip at any time. But the old person was ashamed of those wrinkles and thought she was ugly. My brain sucked that one up. But now I realize that it is health and vitality that is beautiful.
