Do you care about animals, and have compassion for the little ones? If so, that makes you a good person.
Are you concerned about diminished mental abilities as you age? That happens to almost everyone who is blessed with a long life.
Are you worried about doing something incredibly stupid and embarrassing? That kind of embarrassment won't kill you; otherwise I'd be deader than Julius Caesar.
Whichever might be true, there are worse things to worry about. I, for example, wonder how horrible world war 3 will turn out to be.
Your comment indicates moral courage and honesty. Those, in turn, indicate strength of character. So I think you'll be fine.
Cheers!
