What to do if i have aspergers and i think i understand facial expression -but i don't like to do it in case i get wrinkles?

Wrinkles can be nice: Please try not to worry about expression wrinkles - if most of your expressions are even a bit positive, they can be quite attractive. A beautiful song lyric says that "the lines upon my face tell you the story of my life" - it is part of what makes us human. By the age of 45 you've earned the right and in your case it's a badge of honor! just smile gently, you'll look fine. Ask someone you trust.
