She hasn’t smiled in over 43 years… on purpose. Tess Christian trained herself from her teenage years to avoid laughing or smiling all to prevent wrinkles. Now in her 50s, she says it worked, claiming she has almost no smile lines or crow’s feet. She still feels happiness, watches comedies, attends weddings and even funerals, but never lets herself break into a smile. Experts say limiting facial movement can reduce some wrinkles… but aging is driven far more by genetics, sun exposure, and lifestyle.
